Meatier meals and more playtime might reduce cats’ toll on wildlife
Simple steps to keep felines happy can also keep more wild birds and mammals alive

Surprisingly simple measures might keep domestic cats from killing a lot of wildlife.

Owners then implemented one of a handful of interventions for six weeks: switching to a grain-free, high-meat commercially available food; playing for five to 10 minutes each day; putting their cat’s normal food in a puzzle feeder; and existing methods like bells or Birdsbesafe collars. Some owners didn’t change anything, but continued tracking their cats.
Cats fed the meat-rich diet brought home 36 percent less prey, on average, than they did before the diet change, the team calculated. For instance, a cat that normally brings home a daily catch would instead return about 20 critters a month. “This might not seem like very much,” McDonald says of the drop. But “a very large cat population means that if this average were applied across the board, it would result in very many millions fewer deaths.”
Felines treated to playtime, which consisted of owners getting their cats to stalk, chase and pounce on a feather toy and then giving cats a mouse toy to bite, returned 25 percent less prey, though that drop came mostly from mammals, not birds. Cats that started using puzzle feeders actually brought home more wildlife. Bells had no discernible effect, while cats fitted with Birdsbesafe collars brought home 42 percent fewer birds, but roughly the same number of mammals, which aligns with previous research.

Given that the study shows that cats fed meatier diets hunted less, perhaps the standard cat fare is not rich enough in nutrients. That, and boredom by cats that don't get enough stimulation, could be the major reason cats that are allowed to run free hunt birds and small mammals.
My three are indoor only cats, but they certainly enjoy watching the birds and squirrels outside - and at least one of them would be very happy to chase them, though that could be that he spent over a month outside when he got loose and returned to his old home and got used to hunting for his food.
