Research overview: FeLV management in shelters and multi-cat homes

Because FeLV spreads through prolonged close contact such as shared bowls, mutual grooming, and bites, managing it in shelters and multi-cat households requires careful testing, isolation, and housing strategy. Guidelines recommend testing at intake, separating infected from uninfected cats, and counseling adopters of positive cats on indoor living and supportive care. The relatively fragile virus does not survive long in the environment, simplifying disinfection. This overview compiles shelter-medicine guidance rather than one citation, describing how transmission biology shapes housing decisions, why retrovirus testing protocols balance accuracy against cost and intake flow, and how thoughtful management allows many FeLV-positive cats to be adopted into appropriate single-cat or all-positive homes rather than being euthanized at intake.
