Do domestic cats kill enough wildlife to justify UK legislation requiring them to be kept indoors?

Yes 11%No 89%815 votes cast

Recent UK studies estimate that 7-11 million outdoor domestic cats return between 37 and 140 million prey items annually, mostly small mammals with around a quarter being birds. A 2025 Scottish Animal Welfare Commission report discussed targeted containment in new housing near sensitive ecosystems, while a parliamentary petition for seasonal indoor requirements and belled collars closed in June 2026 without triggering a debate. No national legislation currently mandates keeping pet cats indoors.

The room did not hear this as a narrow wildlife-management question. It heard a test of whether the state should reorder ordinary pet ownership, and the scale of the No victory left little appetite for that leap.

The strongest No case turned the proposal into a warning about where regulation would end: “If you're going to do this you might as well just be honest and ban cat ownership.” Another highly respected voice blamed “massive habitat destruction” rather than “the family tabby”, while others called the measure cruel, impossible to police and disproportionate.

The Yes side had a substantive case, even if it was badly outnumbered: “There's no doubt they take tens of millions of birds and small mammals a year in the UK,” argued its best-rated contribution, adding that indoor cats can live contentedly elsewhere. A quieter Yes voice also framed containment as protection for cats themselves; the two sides largely talked past each other, one weighing concentrated predation against wildlife declines, the other human freedom and animal welfare.

The floor’s compromise instinct was clearer than its appetite for legislation. Several No voters allowed a case for bells, population control or targeted restrictions near endangered populations, with one calling a national rule “the easy target”; the ecological exchange then split over whether cats had replaced lost predators, or instead hunted prey at unnaturally high urban densities.

The room was not denying that cats kill wildlife. It was rejecting the leap from that fact to a blanket national duty to keep them indoors.

“I dithered on this one. I have two rescue cats who have always lived indoors. They have toys, warm beds, and no desire to be outside. I voted yes not only because of the aspect of killing wildlife - yes, they’re hunters and cats are useful on farms for rat control - but also from the viewpoint of protecting cats. So many things on my facebook feed daily about strays, kittens being dumped, cats bei”

If you're going to do this you might as well just be honest and ban cat ownership.

Humans are the biggest negative impact on wildlife. Taking down their habitats for net zero plans hasn't helped nor has expanding out instead of up.

I mean, this is peak nanny state rubbish. Cats have been roaming outside and keeping rat numbers down for centuries. If songbirds are declining, maybe blame developers concreting over the greenbelt and massive habitat destruction not the family tabby

Let's take this idea to its logical conclusion. Dogs attack people, so they should be kept indoors. Oh, and foxes kill wildlife, so they should be indoors too. And mink. And weasels. And eagles. Crazy, isn't it? Thoughtful thinking suggests that predators (including domestic cats) make the prey population more healthy by removing the weak, so improving the quality of survivors. It also means more resources are left for the survivors.

In reality this couldn't be policed. There are many stray and feral cats. They would have to be murdered. We animal lovers would not stand for such cruelty. There are house cats but many of those have reasons such as health issues. However a normal healthy cat needs their freedom to stay healthy. To have to contain an outdoor cat would be too cruel. Cats have been around a long time they won't cause extinction of any wildlife. The ones they hunt are many.

No. It’s a ridiculous and disproportionate idea.

Cats are both indoor and outdoor animals i see no reason to change this, perhaps outdoor ones should have collars with bells for the safety of wildlife though.

It's cruel to restrict cats, previously free to roam outdoors. Reducing expression of natural cat behaviour to suit human mores is just wrong. The issue of cat population density has arisen from human population growth, not a natural imbalance in the success of cats. Humans fiddling with natural balance doesn't normally end well. Either other predators' numbers would grow to fill the void or the prey would grow and become something else 'to fix'.

Predation is part of nature. There might be a case in small areas near particular endangered populations but not for a blanket rule.

Cat's are wild roaming creatures, they don't attack people, act as pest control on farms, will sometimes when in the mood, deal without of control mice nests and just generally fluffy. with bad attitudes.
