Toxoplasmosis in Cats: Symptoms, Diagnosis, Treatment, and Human Risks

Table of Contents

Introduction:

Understanding feline health requires balancing everyday care with awareness of potential infections. Among the various parasitic conditions that affect felines, toxoplasmosis is one of the most widely discussed yet frequently misunderstood. Addressing this topic begins with understanding Toxoplasmosis in Cats, a condition caused by the microscopic single-celled parasite Toxoplasma gondii. While cats serve as essential hosts in the parasite’s life cycle, acquiring an infection does not automatically mean every feline will become visibly ill, nor does household exposure guarantee human disease.

In many cases, felines carry the parasite without showing outward illness. However, when clinical disease develops, signs can vary significantly depending on which body systems are affected. Common feline manifestations include fever, lethargy, reduced appetite, respiratory distress, ocular abnormalities, or neurological signs. Diagnosing the condition presents a distinct challenge for veterinary professionals because these symptoms closely mirror those of several other feline illnesses. Furthermore, treatment approaches depend heavily on whether a feline is actively sick or simply carries dormant tissue cysts.

Beyond feline health, this infection frequently raises significant concern regarding human exposure, particularly for pregnant individuals and those with compromised immune systems. This comprehensive guide will explore the symptoms, transmission routes, diagnostic testing, treatment options, prevention measures, overall prognosis, and critical indicators for when to seek immediate veterinary care.

What Is Toxoplasmosis in Cats?

Toxoplasmosis is an infection caused by the intracellular protozoan parasite Toxoplasma gondii. Capable of infecting virtually all warm-blooded animals—including birds, livestock, rodents, and humans—the parasite occupies a unique ecological niche because felines, both wild and domestic, are the only hosts in which it can complete its full reproductive cycle.

When a feline comes into contact with the parasite, the organism invades intestinal cells before potentially spreading throughout the body via the bloodstream and lymphatic system. Despite this widespread movement, a vast majority of infected felines possess immune systems capable of suppressing the parasite, causing it to encyst harmlessly in tissue. Consequently, positive exposure or a positive antibody test does not mean a feline is suffering from severe, active disease.

What Is Toxoplasma gondii?

Toxoplasma gondii is a versatile parasite with a complex life cycle involving three main infectious stages:

Tachyzoites: Rapidly multiplying forms responsible for tissue damage and clinical disease during an active infection.
Bradyzoites: Slowly multiplying forms that aggregate inside tissue cysts (predominantly in muscle and brain tissue) during latent, inactive phases.
Oocysts: Spore-like environmental stages produced exclusively in the intestinal tract of felines and shed through their feces.

Understanding the distinction between asymptomatic infection (where the parasite resides silently in tissue cysts) and clinical toxoplasmosis (where rapid multiplication causes tissue inflammation) is essential for evaluating a feline’s health status.

How Do Cats Become Infected?

Felines typically contract the parasite through specific environmental or dietary routes:

Primary Transmission Route	Description
Ingesting Infected Prey	Hunting rodents, birds, or small mammals containing tissue cysts represents the primary transmission route for outdoor or free-roaming felines.
Consuming Raw Meat	Ingesting raw or undercooked meat, unpasteurized dairy, or contaminated offal can introduce live tissue cysts into the digestive system.
Environmental Exposure	Accidental ingestion of sporulated oocysts from contaminated soil, water, or outdoor areas where other felines have defecated.
Congenital Transmission	Transplacental transmission from a mother to her kittens during pregnancy, which typically occurs if the mother acquires a primary infection while pregnant.

Why Are Cats Important to Toxoplasma?

Felines are classified as the definitive hosts for Toxoplasma gondii. This means that the parasite can undergo sexual reproduction only within the intestinal tract of a feline. Following a primary infection, a feline may shed millions of unsporulated oocysts in its feces for a brief period—typically lasting one to three weeks. Once in the environment, these oocysts undergo sporulation within 1 to 5 days, becoming highly resistant to temperature fluctuations and environmental degradation. Through this unique role, felines facilitate the distribution of the parasite into the broader environment, where intermediate hosts can ingest it.

What Are the Symptoms of Toxoplasmosis in Cats?

Most felines infected with Toxoplasma gondii remain completely asymptomatic throughout their lives. Clinical toxoplasmosis occurs primarily when an immunocompromised system, young age, or high parasitic load allows tachyzoites to multiply unchecked, leading to localized or systemic tissue inflammation.

When clinical disease manifests, non-specific systemic signs often appear first:

Persistent or recurring fever
Pronounced lethargy and depression
Loss of appetite (anorexia)
Progressive weight loss
Respiratory issues, such as tachypnea (rapid breathing) or dyspnea (labored breathing)
Gastrointestinal signs, including occasional vomiting or diarrhea
Severe muscle soreness or stiffness

Because these clinical signs mimic numerous other feline conditions, a systematic approach is necessary to identify the true underlying issue.

What Does Toxoplasmosis Look Like in a Cat?

There is no single “classic” appearance for a feline with toxoplasmosis. An infected feline might appear entirely healthy, present with mild, vague fatigue, or suffer from severe organ failure. The physical appearance depends entirely on which organ systems experience the most acute cellular disruption—most commonly the lungs, eyes, central nervous system, liver, or muscles.

Toxoplasmosis in Cats: Neurological Signs

When tachyzoites migrate to the central nervous system, inflammatory reactions (encephalitis or myelitis) produce distinct neurological deficits. Owners and veterinary teams may observe:

Ataxia (loss of coordination, staggering, or unsteadiness)
Paresis or weakness in the limbs
Head tilts, involuntary eye movements (nystagmus), or circling
Muscle tremors or localized muscle twitching
Partial or generalized motor seizures
Marked behavioral alterations, stupor, or disorientation

Because neurological impairment can stem from trauma, toxins, or infectious diseases like Feline Infectious Peritonitis (FIP), prompt veterinary evaluation of these signs is essential.

Toxoplasmosis in Cats and Eye Problems

Ocular manifestations are among the most frequent clinical findings in active feline cases. The parasite causes focal or diffuse inflammation within the eye structure, leading to condition-specific symptoms:

Uveitis: Anterior or posterior ocular inflammation resulting in squinting, redness, and cloudiness.
Anisocoria: Unequal pupil sizes or abnormal light reflexes.
Retinal Changes: Retinal detachment, hemorrhages, or chorioretinitis.
Vision Impairment: Sudden or progressive loss of sight.

Attempting to diagnose the condition based solely on visual inspection of the eyes is unreliable, as conditions such as Feline Leukemia Virus (FeLV), Feline Immunodeficiency Virus (FIV), and fungal infections produce identical ocular abnormalities.

How Is Toxoplasmosis in Cats Diagnosed?

Establishing a definitive diagnosis of active clinical toxoplasmosis requires synthesizing physical examination findings, patient history, laboratory diagnostics, and response to targeted therapy.

Diagnostic Stage	Key Considerations & Actions
1. Clinical History	Evaluating exposure risks such as hunting habits, raw meat ingestion, or outdoor access.
2. Baseline Diagnostics	Running complete blood counts (CBC) and serum biochemistry panels to evaluate liver, kidney, and muscle enzymes.
3. Serological Testing	Testing IgM titers (indicating active or recent infection) and IgG titers (indicating past exposure or rising acute infection).
4. Advanced Testing	PCR assays on cerebrospinal fluid (CSF), ocular fluid, or tissue samples to confirm parasite presence.
5. Diagnostic Imaging	Thoracic radiographs or abdominal ultrasound to check for pulmonary, hepatic, or pancreatic involvement.

How Is Toxoplasmosis Tested in Cats?

Veterinary clinicians utilize specific laboratory methods to evaluate infection status:

Serological Testing (Antibody Titer Tests):
- IgM Antibodies: Elevated levels suggest a recent, active, or acute infection. IgM titers rise rapidly within 1 to 2 weeks of exposure and decline over several weeks to months.
- IgG Antibodies: Indicate past exposure and immune response. A single high IgG titer simply confirms prior infection. However, a fourfold or greater increase in paired IgG titers measured 2 to 4 weeks apart strongly supports active, ongoing disease.
Polymerase Chain Reaction (PCR) Testing:
- Detects parasite DNA in fluid or tissue samples, such as cerebrospinal fluid (CSF), aqueous humor from the eye, or bronchoalveolar lavage fluid. A positive PCR confirms parasite presence in that location.
Fecal Flotation:
- Rarely useful for diagnosing clinical disease in individual felines, as shedding of oocysts occurs for only a brief period (1–3 weeks) after primary infection, often long before clinical signs manifest.

Can a Positive Test Mean My Cat Is Sick?

A positive test does not automatically confirm that a feline is clinically ill from toxoplasmosis. Many healthy felines test positive for IgG antibodies, indicating successful immune control over a past exposure. Conversely, a feline suffering from acute, fulminant disease may initially yield negative antibody titers before the immune system mounts a detectable response. Consequently, diagnostic results must be interpreted alongside physical signs and overall clinical presentation.

Cat Toxoplasmosis Treatment: What Helps?

When a feline presents with active, clinical toxoplasmosis, immediate veterinary intervention is required. Treatment aims to suppress parasitic multiplication, reduce tissue inflammation, and provide supportive stabilization.

Treatment Category	Specific Interventions
Antiparasitic Medication	Clindamycin is the primary drug of choice to halt tachyzoite multiplication. Alternatives include trimethoprim-sulfamethoxazole or azithromycin under strict veterinary guidance.
Anti-inflammatory Care	Ophthalmic corticosteroid drops or anti-inflammatory therapies to reduce eye inflammation (uveitis) and prevent secondary glaucoma.
Supportive Maintenance	Intravenous fluids for dehydration, oxygen therapy for respiratory distress, nutritional support (feeding tubes if anorexic), and anti-nausea medications.

Therapy must be continued for several weeks—typically 2 to 4 weeks—or for at least two weeks past the resolution of clinical signs to minimize the risk of relapse.

Does Every Cat With Toxoplasma Need Treatment?

No, non-clinical felines do not require treatment. Felines that show positive antibody titers but display no symptoms, normal energy levels, and healthy appetites should not be given antiparasitic medications. Unnecessary treatment does not eradicate tissue cysts and can cause adverse gastrointestinal effects.

How Quickly Can a Cat Improve?

Response to therapy varies based on organ involvement and overall health. Many felines begin showing clinical improvement within 24 to 48 hours of starting appropriate antiparasitic therapy—particularly regarding fever reduction and appetite recovery. However, neurological deficits or severe ocular inflammation may require extended treatment schedules and longer recovery periods.

Can Toxoplasmosis Kill Cats?

While the majority of exposures result in subclinical infections, toxoplasmosis can be severe and life-threatening in high-risk patients. Mortality typically results from acute tissue damage in vital organs, such as necrotizing pneumonia, widespread hepatic necrosis, or severe encephalitis.

Which Cats May Be at Greater Risk?

Neonates and Young Kittens: Transplacentally infected kittens often develop severe, systemic clinical disease affecting the lungs, liver, and brain, carrying a poor prognosis.
Immunocompromised Felines: Cats co-infected with Feline Leukemia Virus (FeLV), Feline Immunodeficiency Virus (FIV), or those receiving immunosuppressive therapy are vulnerable to severe disease or reactivation of latent cysts.
Felines with Advanced Co-morbidities: Concurrent chronic kidney disease, severe diabetes, or oncology treatments can diminish cellular immunity.

What Signs Mean My Cat Needs Urgent Veterinary Care?

Seek emergency veterinary evaluation if a feline displays any of the following critical warning signs:

Severe, sudden respiratory distress or gasping for air
Recurrent or prolonged seizure activity
Acute, severe neurological impairment or collapse
Sudden loss of vision or cloudiness in the eyes
Continuous refusal to eat or drink for more than 24–48 hours
Rapid, unexplained physical deterioration

How Does Toxoplasmosis Spread From Cats?

Understanding transmission mechanics is critical for reducing health risks in both animals and humans. Distinguishing direct contact from environmental vectors helps prevent unnecessary anxiety.

Infection Pathway

Infected Feline: Sheds unsporulated oocysts in its feces for 1 to 3 weeks following initial infection.
Environmental Maturation: Fecal oocysts require 1 to 5 days in the environment to sporulate and become infectious.
Transmission to Others: Other animals or humans contract the parasite by ingesting sporulated oocysts via contaminated soil, unwashed produce, or uncleaned litter boxes, or by ingesting encysted meat.

Can Toxoplasmosis Spread From One Cat to Another?

Direct, casual transmission between adult felines—such as through grooming, sharing water bowls, or sleeping together—is extremely unlikely. Felines do not shed the parasite in saliva, respiratory secretions, or urine under normal conditions. Transmission between felines occurs almost exclusively through:

Consuming infected tissues or prey containing bradyzoite cysts.
Ingesting sporulated oocysts from contaminated soil or shared litter boxes where feces have sat for several days.
Transplacental transfer from an infected queen to her developing fetuses.

How Long Can Toxoplasma Remain in the Environment?

Unsporulated oocysts excreted in fresh feline feces are not immediately infectious. They require a maturation process called sporulation, which takes between 1 and 5 days depending on environmental temperature and humidity. Once sporulated, these oocysts are exceptionally durable. Protected by a thick outer shell, they can remain viable in moist soil, sandboxes, freshwater, and agricultural environments for over a year, resisting standard chemical disinfectants.

Toxoplasmosis in Cats to Humans: What Owners Need to Know

The zoonotic potential of Toxoplasma gondii often causes concern for pet owners. While humans can contract toxoplasmosis, owning a pet feline does not mean a household will become infected.

Can You Get Toxoplasmosis From Your Cat?

Direct contact with a pet feline is rarely the primary route of human exposure. Environmental contamination and foodborne vectors pose significantly higher risks. Humans typically acquire the parasite through:

Consuming undercooked or raw meat (especially pork, lamb, venison, or beef) containing tissue cysts.
Ingesting unpasteurized goat’s milk or contaminated, unwashed produce.
Accidental ingestion of sporulated oocysts through soil exposure during gardening or landscaping without proper hand hygiene.
Consuming unpasteurized drinking water contaminated with sporulated oocysts.
Handling contaminated litter boxes containing feces that have sat uncleaned for longer than 24 hours.

Can You Get Toxoplasmosis From Petting a Cat?

Petting or holding a feline carries minimal risk. T. gondii oocysts are not found on feline fur under normal circumstances because felines groom frequently, removing fecal residues before sporulation occurs. Risk is primarily tied to accidental ingestion of sporulated material from unwashed hands following garden or soil work, or handling aged fecal matter.

Toxoplasmosis and Pregnancy: What Should Cat Owners Know?

Toxoplasmosis poses its highest risk to humans during pregnancy. Primary infection acquired during gestation can be transmitted transplacentally to the fetus, potentially resulting in congenital toxoplasmosis. Potential fetal complications include miscarriage, stillbirth, microcephaly, hydrocephalus, or late-onset ocular impairment (chorioretinitis) and intellectual disabilities later in childhood.

Does Pregnancy Mean You Must Give Up Your Cat?

No, pregnant individuals do not need to surrender or rehome their pet felines.

Major health organizations—including the Centers for Disease Control and Prevention (CDC) and the American College of Obstetricians and Gynecologists (ACOG)—emphasize that simple hygiene precautions effectively mitigate risk:

Prevention Measure	Action Steps
Delegate Litter Duty	Ask a non-pregnant household member to handle litter box cleaning throughout the pregnancy.
Scoop Daily	Clean litter boxes daily. Because oocysts require 1 to 5 days to sporulate, daily removal prevents feces from becoming infectious.
Wear Protection	If litter cleaning cannot be delegated, wear disposable gloves, scoop daily, and wash hands thoroughly with soap and water.
Maintain Indoor Status	Keep cats strictly indoors to prevent hunting, and do not feed raw meat diets.
Garden Safely	Wear gloves while handling garden soil or sandboxes, and wash hands thoroughly after contact.

How Can You Prevent Toxoplasmosis?

Preventing toxoplasmosis requires a combination of feline care practices, litter management, and food safety protocols.

Reduce Your Cat’s Exposure

Keep felines strictly indoors to reduce access to intermediate hosts like wild rodents and birds.
Refrain from feeding raw, undercooked, or unpasteurized diets. Provide commercially prepared canned or dry foods, or properly cooked homemade meals.
Block access to outdoor water sources, puddles, or areas where wild animals congregate.

Practice Safer Litter Hygiene

Scoop litter boxes daily to eliminate feces before potential oocyst sporulation occurs.
Wash hands thoroughly with soap and water after cleaning litter pans.
Use litter box liners and periodically disinfect pans with boiling water (which neutralizes oocysts). Note that many standard chemical cleaners do not reliably kill sporulated oocysts.
Position litter pans away from human food preparation and dining areas.

Protect Yourself During Gardening

Wear sturdy, impermeable gloves when working with garden soil, sand, or outdoor landscaping where outdoor felines may have defecated.
Keep children’s sandboxes securely covered when not in use.
Wash hands, forearms, and fingernails thoroughly after outdoor soil contact.

Food Safety Matters Too

Food safety precautions reduce human exposure to potential non-feline sources of infection:

Cook meats to safe internal temperatures verified by a meat thermometer:
- Whole cuts of meat: At least 145°F (63°C) followed by a 3-minute rest.
- Ground meats: At least 160°F (71°C).
- Poultry: At least 165°F (74°C).
Thoroughly peel or wash all fresh produce under running water prior to consumption.
Wash cutting boards, knives, countertops, and hands with warm soapy water immediately after handling raw meat.

Toxoplasmosis in Cats: Prognosis and Recovery

The prognosis for felines diagnosed with toxoplasmosis varies based on the affected organ systems, immune status, and the speed of treatment intervention.

Can Cats Recover From Toxoplasmosis?

Many immunocompetent adult felines with mild to moderate disease recover fully when treated promptly with appropriate antiparasitic medications. Respiratory and systemic symptoms often resolve within 1 to 2 weeks. However, cases involving severe neurological damage or extensive ocular inflammation may leave residual deficits or require prolonged monitoring to manage secondary complications like vision loss.

Can Toxoplasmosis Come Back?

Yes, recurrence is possible. Because antiparasitic treatments suppress active tachyzoite proliferation but do not clear encysted bradyzoites, the parasite remains dormant within host tissues indefinitely. If a feline later experiences severe immunosuppression (e.g., developing FeLV, FIV, or undergoing chemotherapy), encysted bradyzoites can reactivate into multiplying tachyzoites, leading to a recurrence of clinical disease.

Toxoplasmosis vs. Other Cat-Associated Diseases

When a feline presents with vague signs like fever, lethargy, or gastrointestinal distress, veterinarians must distinguish parasitic conditions like toxoplasmosis from other infectious diseases.

For instance, bacterial gastrointestinal illnesses such as Salmonella in Cats: Symptoms, Treatment, Recovery and Prevention

cause acute vomiting, severe diarrhea, and dehydration, primarily affecting the digestive tract rather than producing neurological or ocular involvement.

When evaluating human health risks associated with pets, it helps to understand that different conditions carry distinct transmission pathways. Conditions like Cat-Scratch Disease: Symptoms, Treatment, Diagnosis and When to Seek Care

stem from bacterial organisms (Bartonella henselae) spread via flea feces and scratch inoculations, operating entirely differently from protozoal life cycles.

Similarly, skin lesions or patchy hair loss in felines are more often caused by superficial fungal infections like Ringworm in Cats: Symptoms, Treatment, How It Spreads and Prevention, which are completely distinct from internal parasitic conditions like toxoplasmosis.

Common Mistakes Cat Owners Make About Toxoplasmosis

Navigating health information can lead to misunderstandings. Avoiding common pitfalls helps ensure safer, better-informed care for both pets and humans:

Assuming Every Exposed Cat Is Clinically Ill: Confusing a positive antibody test with active clinical disease can lead to unnecessary worry and inappropriate medical treatment.
Attempting to Diagnose Based on Symptoms Alone: Relying solely on signs like fever or ocular cloudiness is unreliable because these symptoms overlap with many other feline conditions.
Believing Indoor Cats Have Zero Risk: While indoor felines face significantly lower exposure risks, feeding raw meat, unpasteurized dairy, or accidental exposure to indoor pests can still introduce the parasite.
Focusing Solely on the Litter Box for Human Safety: Overlooking undercooked meat, unwashed produce, and contaminated garden soil neglects the most common routes of human exposure.
Stopping Treatment Prematurely: Discontinuing prescribed antiparasitic medications as soon as a feline shows minor improvement can lead to treatment failure and symptom relapse.
Administering Unprescribed Medications: Attempting to treat a feline with human medications, leftover antibiotics, or unverified home remedies can lead to dangerous toxicity.

What Should You Do If You Suspect Toxoplasmosis?

If you suspect your feline is showing signs of clinical toxoplasmosis, follow this structured action plan:

Step	Recommended Action
1. Record Symptoms	Document specific changes in appetite, energy, breathing, eyes, balance, or temperature.
2. Contact Your Vet	Schedule an evaluation and inform the clinic of progressing symptoms.
3. Detail History	Share information regarding outdoor access, hunting habits, and diet (e.g., raw meat exposure).
4. Avoid Self-Treatment	Do not administer human medications, leftover drugs, or unverified supplements.
5. Complete Diagnostics	Work with your vet to run blood panels, antibody titers, or imaging to confirm diagnosis.

When Should You Contact a Veterinarian?

Timely veterinary care can prevent irreversible organ damage or severe complications.

Care Category	When to Seek Care	Key Indicators
Standard Appointment	Non-emergency evaluation within 24–48 hours	Mild lethargy, persistent low-grade fever, gradual appetite reduction, or mild eye discharge.
Emergency Visit	Immediate, urgent evaluation	Severe respiratory distress, active seizures, acute collapse, sudden vision loss, or disorientation.

Simple Toxoplasmosis Prevention Checklist

Keep cats strictly indoors to prevent hunting of rodents and birds.
Provide commercially prepared canned/dry foods; avoid raw or undercooked meat.
Maintain routine veterinary examinations and preventative health plans.
Consult a veterinarian promptly if unexplained fever, eye changes, or lethargy occur.

For the Household

Clean and scoop litter boxes daily.
Wash hands thoroughly after handling litter pans, raw meat, or garden soil.
Wear gloves during garden work or landscaping.
Cook all meat to recommended internal temperatures.
Wash all produce thoroughly under running water prior to consumption.
Keep food preparation surfaces clean and sanitized.

For Pregnancy or High-Risk Individuals

Delegate litter box cleaning to another household member whenever possible.
Wear disposable gloves if litter cleaning must be self-performed, and wash hands thoroughly after.
Keep household felines indoors and maintain safe feeding practices.
Avoid acquiring new or stray felines during pregnancy.

Toxoplasmosis in Cats: The Bottom Line

Understanding Toxoplasmosis in Cats involves recognizing the balance between parasitic biology, feline medicine, and human health precautions. Caused by Toxoplasma gondii, this condition is common among warm-blooded animals, though felines serve uniquely as the definitive hosts. Fortunately, many infected felines remain subclinical and never develop active disease.

When clinical toxoplasmosis does occur, it can affect vital organ systems, including the eyes, lungs, and central nervous system. Because symptoms mirror many other illnesses, accurate diagnosis requires veterinary evaluation using clinical exams, history, and serological testing. Treatment with targeted antiparasitic medications is effective when initiated promptly.

For humans—particularly pregnant individuals and those with compromised immune systems—managing exposure risk focuses on proper food preparation, garden hygiene, and daily litter box cleaning rather than surrendering pet cats. By maintaining good hygiene practices, keeping felines indoors, and seeking prompt veterinary care when illness arises, cat owners can keep their homes and pets safe.

Frequently Asked Questions About Toxoplasmosis in Cats

Can humans get toxoplasmosis from cats?

Yes, human infection is possible, primarily through the accidental ingestion of sporulated parasite oocysts. However, direct contact with a pet feline is rarely the primary transmission route. Consuming undercooked meat, unwashed produce, or handling contaminated garden soil represents a higher transmission risk for humans than normal interactions with a pet feline.

Can an indoor cat carry toxoplasmosis?

Yes, an indoor feline can carry the parasite if exposed prior to living indoors or if fed raw meat, undercooked offal, or unpasteurized dairy. Additionally, indoor access by prey animals like mice or insects can introduce exposure opportunities. However, strictly indoor felines that eat cooked commercial diets face a significantly lower overall risk.

Does toxoplasmosis kill cats?

Toxoplasmosis can be life-threatening in severe cases, particularly for neonates, young kittens, or severely immunocompromised felines co-infected with FeLV or FIV. However, many infected adult felines do not develop severe illness and recover well with prompt veterinary treatment.

How is toxoplasmosis diagnosed in cats?

Veterinarians diagnose toxoplasmosis by combining clinical findings, physical examinations, advanced imaging, and laboratory testing. Serological antibody titer tests (measuring IgM and IgG levels) or PCR testing on tissue fluids help confirm active parasitic activity alongside clinical signs.

Can toxoplasmosis in cats be prevented?

While complete prevention can be challenging, risk is reduced by keeping felines indoors, preventing hunting, and avoiding raw meat diets. Daily litter box cleaning, proper handwashing, thorough food preparation, and wearing gloves while gardening effectively minimize transmission risks for household members.
