Bee Stings and Snakebite in Cats: First Aid That Buys Time

A sting on the paw is painful. A sting on the muzzle, lip, or inside the mouth is an airway emergency, because swelling there can close a cat's throat in 15 to 30 minutes. Snakebite is the opposite problem: the bite looks minor, the cat seems fine for an hour, and the tissue under the skin is already dying. Both cases share one first rule, which is to handle the cat as little as possible and call the clinic while you are still at home.

Facial and mouth stings: the airway comes first

Cats chase bees with their faces, so the muzzle, eyelids, lips, and tongue take most hits. Swelling on the outside of the face looks dramatic and is rarely dangerous. Swelling inside the mouth, on the tongue, or at the back of the throat is different: that tissue is loose and expands fast, and a cat's airway is about the width of a pencil.

Watch for these in the first 30 minutes: noisy or open-mouth breathing, drooling that will not stop, pawing at the mouth, a tongue that looks swollen or hangs outside the mouth, or gums turning pale or blue. Any one of them means drive now rather than observe. If breathing is already loud and labored, follow the positioning advice in choking and breathing trouble while someone else starts the car.

Remove the stinger without squeezing it

Honeybee stingers stay behind with a venom sac attached. Wasps and hornets usually leave nothing and can sting several times. If you can see a dark needle standing in the skin, the sac is still pumping, so scrape it off sideways with the edge of a credit card, a fingernail, or the back of a knife blade. Tweezers are fine only if you grip the stinger itself and not the sac above it.

Do not squeeze, do not suck, do not apply cream.

Cold for 10 to 15 minutes

A cold pack wrapped in a thin towel, 10 to 15 minutes on and 10 minutes off, slows swelling and dulls pain. Never put ice directly on skin, and never press a cold pack onto a swollen eyelid hard enough to hold it shut. Repeat up to 3 times in the first 2 hours.

Most vets treat a simple sting with an antihistamine injection and, when swelling is severe, a short course of steroids. Do not give human antihistamines at home. Diphenhydramine doses for cats are small and easy to overshoot, many combination products contain decongestants that are toxic to cats, and the drug is too slow to matter in an airway case. Whatever is in your cupboard is a reason to call.

When it is anaphylaxis

Anaphylaxis is a whole-body reaction, not a big lump. It usually starts within 5 to 30 minutes of a sting, and cats show it differently from dogs and people: the early signs are vomiting, sudden weakness, wobbly walking, and fast shallow breathing, not a rash. Some cats collapse, some have diarrhea, and some simply go quiet and hide with pale gums.

Vomiting or diarrhea within 30 minutes of a sting, a cat that cannot stand steadily, or a resting breathing rate over 40 breaths per minute all mean emergency care now. Anaphylaxis needs injected epinephrine, fluids, and oxygen. At home there is nothing useful beyond keeping the cat warm, flat, and driving. Cats that get through the first hour usually recover fully.

Snakebite: what not to do

Cutting an X over the fang marks, sucking out venom, tourniquets, and ice all cause harm. Cutting opens a wound that will not heal and pushes venom deeper. Suction removes almost nothing and adds infection risk from your mouth. A tourniquet concentrates venom and tissue damage in one limb and can cost the leg. Ice damages skin that is already short of blood.

• No cut, no suction, no tourniquet, no ice.
• Keep the cat calm and still; carry it instead of letting it walk.
• Keep the bitten limb at or below heart level, and take off collars and harnesses before swelling starts.
• Do not wash the wound if you can avoid it, because venom on the fur helps identification.
• Photograph the snake from 2 or 3 meters away; never try to catch or kill it.

Immobilize, note the snake, and go

Movement pumps venom through the lymphatic system, so a carried cat absorbs it more slowly than a walking one. Put the cat in a carrier, cover it with a towel, and keep the car cool. On the way, note the four things the vet will ask: the time of the bite, the snake's color and pattern, its length and head shape, and where on the body the cat was bitten. If the snake is dead, do not pick up the head; a dead viper can still bite by reflex.

The antivenom clock

Antivenom works best in the first 4 to 6 hours after a bite, and it is still worth giving up to 24 hours in a cat that is getting worse. It does not repair tissue that is already destroyed; it neutralizes venom still circulating. That is why the decision to drive is made on the bite itself, not on how the cat looks. Cats often appear normal for 1 to 2 hours and then swell quickly.

Expect blood work at 6 and 12 hours to check clotting times and kidney values, and expect swelling to keep spreading for 24 to 48 hours even with treatment. The pit vipers that bite cats most often in China are the short-tailed pit viper (Gloydius brevicaudus, 短尾蝮), common in farmland and rough grass at dusk, and the bamboo viper (Trimeresurus stejnegeri, 竹叶青), bright green with a rust-red tail, which sits in bushes and low trees. Both cause local swelling and bleeding problems, and both respond to antivenom. Treated cats usually survive with a painful, swollen limb for about a week; untreated cats can die of bleeding or kidney failure within 2 to 4 days. Keep the cat indoors for 2 weeks after discharge and check the wound daily for black skin.

In the next hour

1. Look inside the mouth and note where the swelling is; never force the jaw open.
2. Scrape off a stinger sideways if you can see one.
3. Cold pack for 10 to 15 minutes, then call the clinic.
4. For a snakebite: no cut, no suction, no tourniquet; carry the cat to the car.
5. Photograph the snake and write down the time of the bite.

Wasps nest under eaves and in ground holes, and a cat that hunts in the garden at dusk meets both insects and snakes. The ground-level hazards are covered in cat-proofing your home, and poisoning first aid covers the unknown-contact case.
