Yes, adult cats can still contract feline panleukopenia, especially if they are unvaccinated or have compromised immune systems. While kittens are most vulnerable due to their underdeveloped immunity, adult cats exposed to the virus—often through contaminated environments or contact with infected cats—can also become seriously ill.
Symptoms in adult cats may include:
- High fever
- Vomiting and diarrhea
- Loss of appetite
- Generalized depression
- Nasal discharge and dehydration
Vaccination is the most effective way to prevent feline panleukopenia. The virus is extremely resilient and can survive on surfaces for up to a year, making it a persistent threat in shelters, multi-cat households, and breeding facilities.
