You open the door in the morning and there it is: a mouse, a lizard, sometimes a small bird, laid out on the mat. The cat sits nearby looking pleased with itself. It had breakfast an hour ago.
It isn’t a sign you’re not feeding it enough, and it isn’t quite a present either. It’s the oldest thing a cat knows how to do.
The short version
- Hunting is instinct. Fed cats hunt too.
- Don’t scold. The cat won’t understand.
- Feed a meat-rich food and play with your cat every day: both cut hunting in a UK trial.
- A brightly coloured collar cover cuts bird catches. Bells did little in the same trial.
- Keep cats in at night, from dusk until after dawn.
- For street cats: regular feeding and neutering.
Why a fed cat still hunts
Cats were never bred to stop hunting. Their wild ancestors lived on many small meals a day, and each one had to be caught, so the urge to stalk and pounce runs separately from the feeling of hunger. As one vet told Live Science, cats are predatory by nature, and a full bowl doesn’t change that.
Some cats hunt all the time, others hardly ever. Emmanuelle Baudry, an ecologist at Paris-Saclay University, found that personality matters: cats their owners described as bold and active brought home more prey than shy ones. Where a cat lives, and how long it spends outdoors, matter too.
Why bring it to you?
Here the honest answer is that nobody knows for sure. There are two main ideas:
- The teacher. Mother cats bring prey back for their kittens, first dead, then alive, so the kittens can learn to hunt. Baudry calls this the main hypothesis: your cat may be treating you as a rather hopeless kitten. It’s a nice story, but it hasn’t been proven, and it’s hard to explain why male cats and cats with no kittens do it too.
- The safe place. Your home is where the cat feels safest. Bringing the catch back means it can eat, stash or play with it in peace, away from other cats. Often it then loses interest, which is why it ends up on the mat.
What to do with the gift
- Don’t scold or punish. The cat won’t link the telling-off with the mouse. It will just learn to be wary of you.
- Clear it away calmly. Use gloves or a bag. Prey can carry fleas, worms and other parasites, which is one more reason to keep the cat’s flea and worm treatment up to date.
- If it’s still alive, move the cat to another room, put a box over the animal, and let it go outside once it’s calm. An injured bird or hedgehog needs a local wildlife rescue. Cat bites often get infected, even when the wound looks small.
The wildlife side, honestly
Cats are lovely. They are also very good hunters, and there are a lot of them. On islands with no native predators, cats have helped drive birds and other animals to extinction. On the mainland the picture is harder to measure, so all the big numbers are estimates.
The best-known is from the United States. In 2013, Scott Loss and colleagues at the Smithsonian pulled together every study they could find and estimated that free-roaming cats there kill 1.4 to 3.7 billion birds and 6.9 to 20.7 billion small mammals a year. They found that cats with no owner cause most of those deaths, and called cats likely the single biggest human-linked cause of death for US birds and mammals.
In Britain, the Mammal Society points to studies of pet cats. One from 2003 found that cats brought home about two animals a month on average, roughly a quarter of them birds. A newer one, from 2025, put it at about 1.5 a month, mostly mammals, which the Society scales up to around 140 million animals a year across the UK. That is an extrapolation, not a count, and the Society is careful to say that how many animals are caught doesn’t on its own show how much damage is done to their populations.
So the truth sits somewhere in between: cats kill a lot of wildlife, the damage depends on the place and the species, and every cat that hunts less helps.
What really cuts hunting
In 2021, Martina Cecchetti and Robbie McDonald at the University of Exeter tested several ideas with 355 cats in 219 homes in south-west England, over 12 weeks:
- Meat-rich food. Switching to a high-meat food with no grain cut the number of animals brought home by 36%. The team thinks some cats on other foods may be short of something they then hunt for, but that isn’t proven yet.
- Play. 5 to 10 minutes a day of play with a toy the cat could chase, pounce on and “catch” cut catches by 25%.
- A bright collar cover. Birdsbesafe covers, a ruff of bright colours over a quick-release collar, cut birds caught by 42%. Birds see colour well. Mice and voles don’t, and their numbers didn’t change.
- Bells. No clear effect overall in this trial. Some cats seem to learn to hunt quietly anyway.
- Puzzle feeders. Catches actually went up, by 33%.
The Mammal Society’s advice adds two more: get your cat neutered, and keep it in at night. A night in, from dusk until a while after dawn, keeps cats away from the hours when many small animals and birds are on the move. Moving bird feeders away from bushes where a cat can hide helps too.
Street cats
A street cat with no one feeding it has to hunt to eat. A colony fed at the same spot every day, with clean water, has much less need to. A colony that’s also neutered stops growing, and over the years shrinks, so there are fewer hunters in the first place. That’s why the kindest thing for the cats and for the birds is the same thing: steady feeding and trap, neuter, return.
Questions people ask
Why does my cat bring me dead animals?
Hunting is instinct, and fed cats hunt too. Your cat may bring prey home because it feels safe there, or, some think, the way a mother brings prey to her kittens. Nobody knows for sure.
Should I punish my cat for bringing prey home?
No. The cat won’t understand why, and it will only learn to be wary of you. Clear the prey away calmly with gloves, and work on cutting the hunting instead.
How do I stop my cat killing birds?
In a 2021 University of Exeter trial, a meat-rich food cut catches by 36% and daily play by 25%. A brightly coloured Birdsbesafe collar cover cut bird catches by 42%. Keeping cats in at night helps too.
Snap the cats at your feeding spot and put them on the map. A colony that’s known, fed and neutered is a colony that hunts less.
