Shelter cats experience significant stress from confinement, unfamiliar environments, and social disruption. Evidence-based enrichment programs dramatically improve welfare and adoption outcomes.
Shelter cat welfare is a critical but under-resourced concern given the enormous numbers of cats passing through shelters annually. Cats are particularly vulnerable to shelter stress because they are territorial animals for whom the shelter environment — with unfamiliar smells, sounds, and cats — is fundamentally threatening to their normal behavioral needs. Stress immunosuppression increases susceptibility to the respiratory infections that spread rapidly in shelter environments, creating a welfare cascade from psychological to physical health compromise. Hiding box provision is one of the simplest and most evidence-supported welfare interventions available — the ability to hide reduces visible stress indicators and presumably improves subjective welfare experience. Group housing for compatible cats in enriched rooms dramatically improves behavioral welfare compared to individual cage housing.
