Cats in shelter environments experience significant stress from confinement, unpredictable handling, and social isolation, and evidence-based enrichment programs improve welfare while increasing adoption rates.
Shelter environments are inherently stressful for cats — small enclosures, unpredictable human approach, noise, and loss of familiar territory create chronic stress that suppresses immunity and worsens behavior. The resulting upper respiratory infections, stress-induced cystitis, and hiding behavior create a self-reinforcing cycle: stressed cats present poorly and adopt slowly, extending shelter stay and increasing stress. Enrichment interventions that provide hiding opportunities, elevated perches, consistent positive human interaction, and sensory enrichment interrupt this cycle. Foster care provides the most complete welfare improvement by removing cats from the shelter environment entirely. Shelters that implement comprehensive enrichment programs see measurable improvements in cat health, behavior, and adoption outcomes simultaneously.
