Bee and wasp stings in cats are fairly common in the warmer months, from spring to autumn. Cats are most often stung on the paw or face. Luckily, the majority of stings only cause mild swelling and irritation. Cats are good at hiding signs of illness, some may not show any obvious symptoms after a sting. Bee and wasp stings are also known as hymenoptera stings.

Serious reactions are rare but they can be life-threatening. Signs of a serious reaction include vomiting, excessive swelling, and breathing difficulties; these need emergency treatment.

What is a bee or wasp sting in cats?

When a bee or wasp stings an animal, they inject their venom into the skin. This venom is the cause of the symptoms that develop.

• Most stings only cause mild reactions, like swelling of the skin and local irritation. These can often be treated at home.

• The symptoms of a sting should clear within 24–48 hours.

• Rarely, cats can develop an anaphylactic reaction. This can be more common with a sting in the mouth or multiple stings. Anaphylactic reactions usually happen within 30–60 minutes but can also occur hours after the sting. These need emergency treatment.

• If your cat accidentally swallows a bee or wasp, don’t panic. The stomach acids help protect them. Mild vomiting and diarrhoea might develop.

• Bees leave their stings in the skin, wasps don’t.

Bee and wasp stings can lead to local irritation and swelling, which can usually be treated at home. Rarely, severe reactions can occur. Our Joii vets are available 24 hours a day; call us now if you have any concerns.

Are some cats more at risk of bee and wasp stings than others?

Bee and wasp stings can affect any cat, regardless of age, breed, or lifestyle. Kittens are naturally very curious so they can be more prone to stings. Outdoor cats tend to be more commonly affected than indoor-only cats.

How are bee and wasp stings diagnosed in cats?

Typically, veterinarians diagnose bee and wasp stings based on the signs exhibited by your cat. Further tests are usually unnecessary unless your cat's symptoms persist for a few days without improvement or suddenly worsen.

What’s the vet treatment for bee and wasp stings in cats?

Mild reactions that are causing excessive irritation may need the following:

• Placing a tube to help with breathing
