Should my cat wear a collar? Safety advice (UK)

No. The collar and tag rule in the Control of Dogs Order only covers dogs. What the law does ask, in England, is that your cat is microchipped by 20 weeks old and that you keep the details up to date.

• PDSA doesn't recommend collars for cats, and says a microchip is the best way to make sure you're reunited.
• Cats Protection says a microchip is the safest way to identify a cat, and that if you do use a collar, a quick-release one is safest.
• International Cat Care sets out both sides: a bell on a collar can reduce the number of birds a cat catches, but collars can also cause injuries.

• Getting caught on a branch or fence and trapped, if the collar doesn't open.
• A front leg slipping through the collar, which can cut into the skin and cause a serious injury.
• The collar catching around the jaw.
• Rubbing, which can make the skin sore and wear away the fur around the neck.

• Choose a quick-release, or snap-open, collar that pops open if it catches on something.
• Avoid collars with elastic in them. They stretch instead of opening, and can cause serious injuries.
• Fit it so you can slide two fingers underneath, then check again after a few minutes, because cats often tense up when a collar goes on.
• Check the release clip regularly: dirt and grease can stop it opening.
• Keep anything on the collar small and light, and replace the collar if it's worn or damaged.
• Kittens grow fast, so check the fit every week or two.

It's easier while they're young. Put the collar on for short spells at first, and keep your cat busy with play, food or treats. If your cat keeps trying to get it off, or it's rubbing, take it off and ask your vet for advice.

PDSA calls flea collars an unreliable way to control fleas. International Cat Care warns that many flea collars sold in pet shops and supermarkets contain permethrin or organophosphates, which are toxic to cats, and only recommends collars from your vet. Ask your vet about flea treatment instead.

A microchip can't fall off, and it's the law for pet cats in England. Keep the details up to date with the database.

A tag on a collar does something a microchip can't: a neighbour can read it without a trip to the vet. If you decide a collar suits your cat, a light QR tag on a quick-release collar lets anyone who finds them scan it with a phone and reach you straight away, while your number stays private.
