Feline panleukopenia is a highly contagious and deadly parvovirus infection that can devastate unvaccinated shelter cat populations, making prevention the primary welfare priority.
Panleukopenia-affected cats suffer severely - profound leukopenia from bone marrow destruction, hemorrhagic diarrhea, and often secondary sepsis create a rapid, extremely painful decline. Shelter outbreaks are particularly devastating as illness spreads to many animals simultaneously, overwhelming staff capacity and resources. Vaccination on intake, isolation protocols, and environmental decontamination are the welfare pillars that prevent panleukopenia from becoming a shelter catastrophe. This is a disease where prevention is not just better but orders of magnitude more effective than treatment.
