Cats and wasp stings

Symptoms of wasp stings in cats

Wasp stings aren't usually something to worry about in cats. However, some cats are allergic, so it’s important to know what signs to look out for.

• Redness, itchiness and swelling at the site of the sting.
• Soreness around the site of the sting – which can last a few hours.

Allergic reactions in cats

When a wasp or bee stings it injects venom into the body.  Just like humans, some cats are hypersensitive to this and can have an allergic reaction.

If your cat has been stung multiple times, their risk of an allergic shock increases. Even if your cat doesn’t normally react to a sting, it could become ill if it comes into contact with particularly aggressive wasps.

What should I do if my cat has been stung by a wasp?

Usually, a wasp sting does not need a vet's attention so you can treat your cat at home. Here  are some things you can do to help:

• If you see that the barb remains, try to remove it.
• Keep your cat under observation for the next few hours.
• Relieve the pain or swelling by applying a cold compress to the area.

When should I contact the vet?

• If your cat seems generally poorly or not themselves 
• If your cat has breathing problems
• You see signs of severe swelling (especially in the face or neck)
• Vomiting and diarrhoea
• If your cat has been stung in the oral cavity and throat
• If you know that your cat has previously had an allergic reaction
• If you have a kitten or an older cat – and they have been stung multiple times

How can my vet help with wasp stings?

If your cat has had an allergic reaction, or if you’re worried, you should take them to the vet. They will give your cat an antihistamine – and possibly local or general cortisone medication.
