Five to ten minutes of play a day: what a study shows about cats and prey brought home
A cat that regularly leaves a bird or a rodent on the doorstep isn't offering a gift: it's expressing a hunting behaviour that domestication left largely intact. A landmark study measured what actually reduces these prey returns. Find all our enrichment ideas in the cat toys and enrichment section.
What a landmark study shows
A study by Cecchetti, Crowley and McDonald, published in 2021 in Current Biology, compared several interventions in cats with free outdoor access: a diet higher in meat content, a bell collar, and daily play sessions with a prey-like toy (study on Google Scholar). Regular play sessions, much like the meat-enriched diet, significantly reduced the number of prey brought home, while the bell collar alone did not produce a comparable effect.
Why play works so well
- Prey-like play satisfies the hunting sequence (spot, stalk, pounce, capture), which lowers the drive to reproduce it outdoors on a real animal.
- Five to ten minutes is enough according to the study, provided the toy moves unpredictably, the way live prey would.
- The effect holds as long as sessions stay regular, unlike a toy left out freely that a cat quickly loses interest in.
How to reproduce this result at home
A wand toy or an articulated toy, actively moved by the owner rather than left still, comes closest to the tested protocol, as covered in our toy rotation method guide. Combining these sessions with a snuffle mat that also engages active foraging reinforces this predatory energy output without it spilling over entirely onto local wildlife.
Frequently asked questions
Does a cat need to be kept fully indoors to protect wildlife?
Not necessarily according to this study: regular play and an adapted diet already noticeably reduce prey returns without strict confinement.
Does an automatic toy produce the same effect as a session with the owner?
The study tested active sessions with the owner; the predictable, repetitive motion of an automatic toy reproduces the unpredictability of real prey less well.
Does that make the bell collar useless?
It can warn some prey, but the study shows a weaker, less consistent effect than daily play or a meat-enriched diet. Find all our guides in the cat hub.
