Cat owners are being urged to keep their pets inside in March and April because of the risk outdoor cats pose to birds during the vital breeding season.
Many birds begin to breed and nest in March and continue into April as the weather warms up, and with the population of many birds under threat in the past three decades, households are being asked to help protect breeding birds where they can, such as leaving food out and avoiding cutting hedges.
While they are one of the most popular pets in the UK, there are fears over the damage which cats may be wreaking on wildlife, particularly outdoor who are allowed to roam freely in , countryside, parks and other open spaces.

But with cats on the prowl, many birds could be lost to cats, who enjoy killing for sport, even though they don’t need to hurt birds to eat.
According to Rebecca Bevan, author of The National Trust Book of Nature Friendly Gardening, cat owners should put a bell on their ’ collars to help protect birds this spring and keep them inside at night.
She writes: “Many people view cats hunting birds and small mammals as part of the natural order of things but domestic cats are descended from African wildcats, which obviously don’t naturally occur in the British countryside.
“Consequently, our native birds and mammals have not evolved to live alongside them and their populations are impacted by the presence of so many pet cats hunting for much of the day and night.
“If you are the owner of a cat, consider putting a bell on its collar to make stalking prey a little harder – it doesn’t need to hunt for food, after all!
“During the season when baby birds are fledging, you could also keep your cat in at night. It is probably best not to encourage birds into gardens patrolled by cats by [putting up] bird feeders or nestboxes but, if you do, be very careful to locate them where cats cannot reach.”
Some experts even go a step further, and urge cat owners not to let their outside at all, day or night, if you live in an area where birds are nesting or hopefully, thriving.
An expert on the RSPB’s ‘Ask An Expert’ forum, IanH, said: “In gardens here in the UK, whilst cats are not threatening any species with extinction, they do kill in excess of 50 million birds each year as well as frogs, slow worms and various small mammals.
“Given these facts there are a few points to consider if you are thinking of bringing a cat into an area where birdlife is thriving.
“Many birds nest in our gardens and baby birds are highly vulnerable. Many species have young that stay on the ground for days after leaving the nest, robins and blackbirds being the most common.
“These species will breed numerous times throughout the summer and a roaming cat can cause mayhem. This is often the reason you hear frantic alarm calls from agitated parent birds.
“Again, keeping the cat indoors is the ideal solution.”
According to Defra, bird populations have decreased by 2% UK-wide since 2018 and 7% in England alone.
Experts have warned that some birds could become extinct if the trend is left unchecked.
Kathryn Brown, climate change and evidence director at the Wildlife Trusts, said: “The decline of wild birds across the UK is tragic. These latest figures are particularly alarming, given the downward trend across all bird species in recent years. Habitat loss, pollution and climate change are all factors that have contributed to these worrying declines.”
