What begins outdoors often follows cats inside.

Across North America, veterinarians continue to see a deadly pattern repeat itself in both feral colonies and family homes. Outdoor cats encounter a virus that is fast, durable, and devastating, then unknowingly carry it back indoors on fur, paws, or shared spaces. The danger is not limited to roaming cats. Indoor cats can be exposed without ever stepping outside. Understanding how this virus moves, survives, and infects helps explain why outbreaks still occur in clean homes and why prevention depends on more than keeping doors closed.
