Feline panleukopenia (parvovirus) causes catastrophic outbreaks in shelters with high mortality, requiring strict vaccination and biosecurity protocols.
Panleukopenia outbreaks in shelters cause catastrophic suffering and mass mortality in vulnerable cat populations. Affected kittens experience profuse hemorrhagic diarrhea, vomiting, profound weakness, and rapidly fatal systemic collapse. The scale of welfare impact in outbreaks - dozens or hundreds of kittens dying painful deaths - is preventable through consistent vaccination at intake, strict biosecurity, and environmental decontamination. Shelters that cut corners on vaccination protocols expose their most vulnerable residents to preventable suffering at massive scale.
