The shelter environment causes significant behavioral and psychological stress in cats, with welfare-centered approaches including hiding spaces, enrichment, and foster programs making measurable improvements.
The shelter is a profoundly stressful environment for cats. Unfamiliar smells, sounds, and the proximity of other cats create chronic fear responses. Cats that cannot hide are in a state of constant threat perception - the stress of having no escape from perceived danger is intense and physiologically damaging. Chronic shelter stress suppresses immune function, reactivating latent herpesvirus and causing respiratory disease that further reduces quality of life and adoptability. The welfare of shelter cats is substantially improved by even simple interventions: a cardboard box to hide in transforms the behavioral state of a frightened cat. The most effective welfare intervention is moving cats out of shelters quickly into foster homes or new adoptive families.
