Cats in shelter environments face unique welfare challenges from confinement, unfamiliar surroundings, and loss of territory that can cause significant stress and illness.
Sheltered cats experience chronic stress from confinement in small spaces, loss of familiar territory and social relationships, exposure to unfamiliar sounds and smells, and unpredictable human contact. This stress causes suppressed immune function, increasing susceptibility to respiratory infections and cystitis. Simple, low-cost interventions dramatically reduce stress: hiding boxes allow cats to feel secure, elevated perches provide choice of position, consistent daily routines reduce unpredictability, and positive handling techniques replace fearful interactions. Reducing length of stay through effective adoption programmes is the most impactful welfare improvement for most shelter cats.
