πŸ“ Summary

Feline panleukopenia (cat distemper) is a highly contagious parvovirus, with infection rates up to 70% in cats under a year and mortality up to 80–90% in young kittens. Vaccination and a clean, disinfected environment are the best defenses.

1 Understanding Feline Panleukopenia

What Is Feline Panleukopenia?

Also called feline distemper or infectious enteritis, it’s a highly contagious acute disease marked by sudden high fever, stubborn vomiting, diarrhea, dehydration, circulatory failure, and a sharp white-cell drop.

Not every low white-cell count is panleukopenia; feline leukemia and hepatitis cause it too.

Kittens Are Most Vulnerable

Unvaccinated or partly vaccinated cats are at risk, especially 3–5 month kittens. An infected queen may have stillbirths, miscarriages, or neuro-symptom kittens. Spread is via virus-laden urine/feces or blood-sucking insects and fleas. The agent is a parvovirus that can survive over a year in the kidneys.

All ages can catch it. Usually under-1 cats are susceptible, with infection up to 70% and death 50–60%; under-5-month kittens can reach 80–90% mortality. Risk falls with age, but group-housed cats can see whole-colony outbreaks.

It occurs year-round, peaking in spring and winter.

Tip:

Vaccinate on scheduleβ€”the most effective prevention. Keep the environment and belongings clean and disinfected, and give vitamins to boost resistance.
