Burn care starts with 20 minutes of cool running water, and nothing else goes on the skin: no ice, no oil or ointment, no toothpaste. Then you watch for 24 hours, because a scald that looks like a pink patch at 8 pm can be an open wound by noon the next day. Size the injury in palms, using the cat's own front paw pad as roughly 1 percent of its body surface: 1 pad is 1 percent, 2 pads is 2 percent, and 2 percent is the line where a vet should see the cat.
The first 60 seconds
Get the cat away from the source without grabbing the burned area. Lift the cat by the scruff and the chest and move 2 metres. For flame, smother with a dry towel for 5 seconds, then put the cat down. Do not use a wet towel on a flame, and do not pull clothing or a collar that is stuck to skin. Turn the tap on first, check the temperature with your inner wrist for 3 seconds, and start water on the burn within 20 minutes. Cooling still helps up to 3 hours after the injury, just less.
20 minutes, counted properly
Cool, not cold: 15 to 20 C is the target, which is tap water at the cool end, not water with ice in it. Run it over the burn for a full 20 minutes, and keep the rest of the body dry and warm with a towel, because a 4 kg cat loses heat fast when wet. Stop early and call a vet if the cat shivers, goes limp, or the gums turn pale. On a kitten under 12 weeks, or a cat under 2 kg, cut cooling to 10 minutes and go to the clinic, since hypothermia is the bigger risk at that size.
Ten minutes is half a dose; 5 minutes is a rinse, and a cat that panics at 6 minutes gets restarted and counted up to 20, with the real number passed to the vet. A jug poured from 10 cm above the skin works when a tap is not an option; a wet cloth pressed on does not.
The 2 don'ts, and 3 more
Ice is the first don't. A 0 C pack on a burn drives blood away from tissue that is already starved, and 5 to 10 minutes of contact can add frostbite to a partial thickness burn. Oil, butter, petroleum jelly and ointment are the second: they hold heat in for 20 minutes or more, seal in bacteria, and have to be scrubbed off under sedation before the wound can be assessed.
- Do not pop blisters; the roof of a 5 mm blister is a sterile dressing.
- Do not apply human creams with zinc or lidocaine; a cat that grooms the area swallows them.
Do cover the burn loosely with cling film or a clean, non fluffy cloth for the trip, and do keep the cat from licking: a soft cone for 24 hours is cheaper than 10 days of antibiotics.
4 depths, which is what the vet is judging
| Depth | What it looks like | Blisters or peel | Shows up at | Action |
|---|---|---|---|---|
| Superficial (1st) | Pink, dry, hair intact, tender | 0 mm, none | 0 to 6 hours | 20 minutes of water, watch 24 hours |
| Superficial partial (2nd) | Moist, bright pink, very painful | 5 to 10 mm blisters | 6 to 24 hours | Vet within 24 hours |
| Deep partial (2nd) | Pale, leathery, less painful than it looks | 1 to 3 mm skin peels | 12 to 48 hours | Same day, wound care and pain relief |
| Full thickness (3rd) | White, grey or charred, no pain, hair pulls out | 3 mm or more of dead skin | 0 to 2 hours | Emergency now, surgery may be needed |
Less pain is worse, not better: a burn that stops hurting has usually destroyed the nerve endings that were reporting it. That single observation is why a quiet cat with a white patch is more urgent than a screaming cat with a pink one.
Sizing it with the palm rule
Use the cat's own front paw pad as 1 percent of its body surface, and count only the areas that are blistered, peeled, white or charred. Five pads, 5 percent, means fluids and pain control, and 10 pads, 10 percent, carries a real shock risk within 6 hours; 20 percent is grave. Do not count simple redness, and do not average: 2 separate 1 percent patches are 2 percent, not 1.
The 24 hour observation window
Burns are progressive: tissue dies over 12 to 48 hours, so hour 24 matters more than hour 1. Photograph it at 0, 12 and 24 hours with the same light and a coin for scale, and go back to the vet if any of 3 things happens: the red edge spreads more than 5 mm, discharge appears, or the cat stops eating for 12 hours. A temperature at or above 39.5 C is a same day call. Keep the cone on for 24 hours.
Smoke adds its own clock: a cat from a fire can look normal and develop breathing trouble 24 to 72 hours later. Over 40 breaths a minute, a hoarse meow or soot on the nose means go now. Electrical burns from a chewed 220 V cord cause mouth ulcers at 24 to 48 hours and lung fluid 12 to 24 hours later, so a vet check is standard even if the cat looks fine.
When to go now, without waiting for 24 hours
- Any burn of 2 percent or more, meaning 2 palm sized areas.
- Face, eyelid, ear canal, paw pad, or genital area, at any size.
- White, charred, or painless skin, which means full thickness.
- Breathing over 40 per minute, or a hoarse cry after smoke.
- A kitten under 12 weeks, a cat under 2 kg, or a cat with a 39.5 C fever.
- Any electrical burn, even a 2 mm mark at the mouth corner.
If the cat licked an ointment or a household cleaner before you stopped it, note the product name; the toxic exposure tool lists which household chemicals need a call rather than a wait, and the hot water scald page covers the kitchen specific cases. Do not induce vomiting for a skin exposure, and do not give human pain medicine: 1 tablet of paracetamol or ibuprofen can be fatal to a 4 kg cat.
Do this in order
- Move the cat 2 metres from the source and smother flame for 5 seconds with a dry towel.
- Run 15 to 20 C water over the burn for 20 minutes, body warm and dry.
- Put nothing on it: no ice, no oil, no ointment, no toothpaste.
- Cover loosely with cling film, cone on, and photograph at 0, 12 and 24 hours.
- Go now for 2 percent or more, a white patch, 40 breaths a minute, or any electrical burn.

Frequently asked
Why 20 minutes of water and not 5?
Cooling removes residual heat from the tissue and limits how deep the injury goes, and the effect scales with time: 10 minutes is roughly half a dose and 5 minutes is a rinse. Use 15 to 20 C water, keep the rest of the body warm and dry, and stop early only if the cat shivers or goes limp.
Can I put ice or an ice pack on a cat burn?
No. Ice constricts the vessels feeding already damaged skin and 5 to 10 minutes of contact can add frostbite on top of a partial thickness burn. Ointments, butter, oil and toothpaste are equally wrong: they trap heat for 20 minutes or more and must be scrubbed off before a vet can judge the wound.
How do I estimate burn size on a cat?
Use the cat's own front paw pad as about 1 percent of body surface and count only blistered, peeled, white or charred skin. Two palms, 2 percent, means a vet visit; 10 percent carries a shock risk within 6 hours. Any burn on the face, paw pad or genital area needs care at any size.
