Feline panleukopenia is a highly contagious and often fatal viral disease that devastates cats' immune systems and gastrointestinal tracts, particularly in kittens.
Panleukopenia causes profound suffering including severe vomiting, bloody diarrhea, high fever, and collapse. Affected kittens experience rapid deterioration and often die within days. Survivors may suffer lasting immune damage. Vaccination campaigns and shelter biosecurity are critical for preventing this agonizing disease.
