FIV-positive cats in colonies require specific management to prevent transmission while maintaining colony welfare. Neutering and stable group composition are key interventions.
FIV-positive colony cats can live in stable managed groups for years without disease progression or transmission to negative cats, provided the colony is neutered and aggression is managed. The welfare cost of separating FIV-positive cats from established social groups is significant — familiarity and social bonds are welfare-positive for colony cats. Regular health screening, parasite control, prompt treatment of infections and good nutrition maintain immune function in positive individuals. Colony managers who understand FIV transmission accurately make better welfare decisions than those operating on misinformation about casual transmission.
