Feline Tularemia
Also known as: Rabbit Fever
⚠ Emergency Warning Signs
Significant fever or illness, particularly with known wildlife exposure, warrants prompt veterinary evaluation.
Overview
A genuinely serious bacterial infection that cats can acquire from hunting or contact with infected wild rodents or rabbits, notable for also carrying real zoonotic (animal-to-human transmission) risk — a genuine concern for both cat and owner health given this dual transmission consideration.
Symptoms
- Fever
- Lethargy
- Enlarged lymph nodes
Causes
Infection with Francisella tularensis bacteria, most commonly acquired through hunting or contact with infected wild rodents or rabbits (either through bite wounds, ingestion during hunting, or contact with infected tissue), or less commonly through tick or biting fly transmission. Caused by Francisella tularensis bacteria, tularemia is typically acquired by cats through hunting and eating infected wild rodents or rabbits, or through tick or biting fly transmission — a genuine zoonotic concern given transmission risk to humans handling an infected cat or exposed to the same wildlife source.
Risk Factors
Outdoor access with hunting behavior, particularly in regions where this bacteria is present in the wild rodent and rabbit population.
Transmission
Acquired through contact with infected wild rodents or rabbits (bite wounds, ingestion, tissue contact), or through tick or biting fly transmission; genuinely notable for zoonotic potential, meaning infected cats can potentially transmit this to human household members through bites, scratches, or contact with infected tissue.
Incubation Period
Typically 1-10 days following exposure before symptoms develop.
Disease Stages & Progression
Following exposure, cats can develop significant systemic illness including fever and lymph node involvement, with the specific presentation depending on the exposure route (such as localized symptoms near a bite wound versus more generalized illness from ingestion exposure).
Early Warning Signs
Fever, lethargy, and decreased appetite, sometimes with localized swelling near an exposure site like a bite wound. Fever, lethargy, and swollen lymph nodes are common signs, sometimes with abscess formation at lymph nodes — this disease can be severe and requires prompt veterinary attention along with appropriate precautions given human transmission risk.
Advanced Symptoms
Significant illness including high fever, enlarged lymph nodes, and in severe cases, more widespread systemic effects.
Diagnostic Methods
A relevant hunting or wildlife exposure history combined with compatible symptoms and specific testing establishes this diagnosis; genuine care is needed in sample handling given zoonotic risk.
Veterinary Examination Process
Assessment of fever, lymph node involvement, and any localized exposure site changes, with appropriate precautions given zoonotic risk.
Recommended Lab Tests
Specific antibody testing or culture, handled with appropriate biosafety precautions.
Diagnostic Imaging
Not primarily diagnostic; blood-based and culture testing are more directly relevant.
Blood Test Indicators
Specific antibody testing or culture (handled with appropriate precautions given zoonotic risk) can confirm this infection.
Biopsy / Histopathology
Not typically the primary diagnostic approach given zoonotic handling considerations.
Differential Diagnoses
Other causes of fever and lymph node enlargement — specific testing combined with relevant wildlife exposure history supports this diagnosis.
Home Monitoring Guidance
Not appropriate for suspected significant infection — needs prompt veterinary evaluation, and given zoonotic risk, appropriate precautions (like wearing gloves when handling a potentially infected cat) are genuinely important for human household members.
Veterinary Treatment Options
Antibiotic treatment addresses this bacterial infection; supportive care addresses symptoms during recovery.
Surgery Requirements
Not typically needed.
Recovery Timeline
Typically improves within 2-3 weeks of appropriate antibiotic treatment.
Possible Complications
Significant illness if not promptly treated; genuine zoonotic risk to human household members requiring appropriate precautions during the cat's illness and recovery.
Long-Term Management
Not typically needed after successful treatment.
Prevention
Reducing hunting exposure through indoor living or supervised outdoor access, and being aware of this zoonotic risk if your cat does hunt in regions where this bacteria is present in wildlife.
Vaccination Availability
No vaccine exists against this infection for cats.
Prognosis
Good with prompt antibiotic treatment.

Frequently Asked Questions
Could I catch this from my cat?
Genuinely, yes, this is a real zoonotic risk — if your cat has this infection, taking appropriate precautions (wearing gloves when handling them, careful hygiene, avoiding contact with any wounds or discharge) is important for protecting human household members, and your doctor should be made aware of this exposure if you develop any symptoms yourself.
