Can Cats Get Lyme Disease?
Cats can be exposed to Lyme disease bacteria through tick bites, but clinical Lyme disease appears less common in cats than in dogs or people.
Yes, cats can get Lyme disease bacteria from infected tick bites. However, compared with dogs, cats appear less likely to develop classic clinical Lyme disease.
How cats are exposed
The risk pathway is straightforward:
- Tick attaches to cat
- Tick remains attached long enough to transmit bacteria
- Cat may become infected
Outdoor cats in wooded or grassy tick-endemic areas face the highest exposure risk.
Do infected cats always get sick?
No. Many exposed cats do not develop obvious illness. When signs occur, they can include:
- Fever
- Lethargy
- Reduced appetite
- Stiffness or lameness
These signs overlap with many other feline conditions, so diagnosis requires caution.
Diagnosis challenges
Veterinarians may use:
- Tick exposure history
- Physical exam
- Blood testing and broader differential workup
A positive exposure test does not always prove Lyme is the cause of symptoms, so clinical context is essential.
Treatment and outlook
When Lyme-associated illness is suspected, treatment may include:
- Targeted antibiotics
- Pain and inflammation support
- Monitoring for response and alternate diagnoses
Most cats with mild signs improve with timely care, but persistent lameness or systemic illness needs follow-up.
Prevention strategy
- Use cat-safe tick prevention recommended by your veterinarian
- Check coat and skin after outdoor exposure
- Keep grass and brush trimmed around home areas
- Remove ticks promptly and correctly
Lyme prevention in cats is mainly about avoiding tick attachment in the first place.
