Domestic Cat Predation: Wildlife Impact and Welfare of Both Species

Pet cats kill significant numbers of wildlife globally. This creates a complex welfare question involving both the welfare of prey animals and the behavioural needs of cats.

Key Facts

UK cats kill an estimated 55 million birds and 275 million mammals annually
Many prey animals survive capture with serious injuries that are rarely followed up
Bell collars reduce predation success by 30-50% when habituation is managed
Cats kept indoors or in cat-proof enclosures have zero predation impact
Keeping cats indoors at dawn and dusk when small mammals are most active reduces kills
High-pitched sonic deterrents on collars (e.g. CatAlert) show promising results

Welfare Considerations

Prey animals that escape cat capture often die slowly from injuries. Birds with puncture wounds from cat claws develop fatal bacterial infections within 24-48 hours in many cases. The welfare of prey animals is a legitimate consideration when managing cat behaviour. Simultaneously, cats have strong predatory instincts that cannot be extinguished. Solutions that reduce predation while meeting cats' behavioural needs include indoor environmental enrichment, play that mimics hunting, and physical barriers.

What You Can Do

Fit a bell and bright collar on outdoor cats to reduce predation success
Keep cats indoors from dusk to dawn during bird breeding season (April to July)
Bring birds to a wildlife rehabilitator immediately if alive after a cat attack
Provide indoor cats with play sessions that simulate hunting (wand toys, puzzle feeders)
Consider a cat-proof garden enclosure to allow outdoor access without predation risk
