Moderate severity

Bee & Wasp Stings

A sudden painful swelling where a curious cat has been stung, most often on the face or paw. Most stings cause only local irritation, but stings inside the mouth or throat, or a rare allergic reaction, can become an emergency.

⚠️ Common symptoms

Sudden pawing at the face or mouth, or licking a pawA firm, painful swelling at the sting siteRedness, heat and obvious tendernessDrooling if the sting is in or around the mouthHives, widespread facial swelling, vomiting, weakness or laboured breathing in an allergic reaction

Cats are natural hunters, and a slow, buzzing bee or wasp is an irresistible target — which is exactly why stings tend to land on the batting paw or the inquisitive face and mouth. In most cases the result is a straightforward local reaction: a sharp yelp or sudden pawing, followed by a firm, hot, painful swelling at the site that settles over a day or two. A bee leaves its barbed sting behind, and scraping it out sideways with a fingernail or the edge of a card removes it without squeezing more venom in; a cool compress then helps with the pain and swelling. Two situations turn a nuisance into an emergency. The first is a sting inside the mouth or throat, common when a cat actually catches the insect, because swelling there can quickly block the airway. The second is a genuine allergic reaction, which may bring hives, dramatic facial swelling, vomiting, weakness, collapse or laboured breathing within minutes. Both demand immediate veterinary attention. Owners should never reach for human antihistamines or painkillers on their own, as doses and even whole drug classes safe for people can poison a cat. Prevention comes down to reducing tempting encounters — screening windows, dealing with wasps safely, and supervising garden time in late summer when stinging insects are at their peak.

🔍 Causes

  • Batting at or biting bees, wasps and hornets
  • Hunting flying insects in gardens or on windowsills
  • Stepping on an insect in grass, leading to paw stings
  • Curiosity about buzzing insects near the face and mouth

🛡 Prevention

Discourage your cat from chasing flying insects indoors and clear wasps from the home safely. Supervise outdoor time in late summer when wasps are most active, keep windows screened, and remove nests near the house using a professional. Learn the signs of a severe allergic reaction so you can act fast if one ever occurs.

💊 Treatment

For a simple sting, keep your cat calm and apply a cool compress to ease pain and swelling; a bee's barbed sting can be scraped out sideways with a fingernail or card rather than squeezed. Do not give human painkillers or medicines unless your vet directs you, as many are toxic to cats. Any sting inside the mouth or throat, any breathing difficulty, or fast-spreading swelling needs emergency veterinary care, where a vet may give antihistamines, steroids or adrenaline.

When to see a vet: Seek emergency care straight away if the sting is inside the mouth or throat, if your cat struggles to breathe or swallow, or if you see widespread swelling, hives, collapse, vomiting or weakness — these can signal a life-threatening allergic reaction. A simple sting that keeps swelling, oozes or is still painful after a day also warrants a vet visit.
