Cat Burns: 20 Minutes of Cool Water, Not Ice

Run cool water over a cat burn for 10-20 minutes, starting inside the first 3 minutes if you can, and put nothing else on it. Ice, butter, toothpaste and oil all make the injury deeper or dirtier, and a burn that covers more than 20% of the body surface needs intravenous fluids, not a bandage. Cooling is the only home treatment that changes how the wound heals.

Water in the first 3 minutes limits the depth

A burn keeps cooking after the heat source is gone, because the skin holds heat for 10-20 minutes. Water at 15-20 C pulls that heat out and can drop surface temperature by 8-10 C within 60 seconds. Water started after 20 minutes still cleans the wound, but it no longer saves tissue. Use the tap or a jug, let it run over the burn, and keep the rest of the cat dry with a towel, because a wet 3 kg cat loses 1-2 C of core temperature in 20 minutes and a burned cat is already losing heat through the damaged skin.

Never ice, and never a frozen pack

Ice sits at 0 to -18 C, constricts the skin vessels that need to stay open, and adds a cold injury on top of a heat injury. A frozen gel pack left on a paw for 10 minutes can turn a partial burn into full-thickness damage. Ice also hurts, and a cat in pain fights the person holding it. If the only cold thing in the house is the freezer, use tap water at 15-20 C and nothing else.

Judge depth and size before you move the cat

Depth	What it looks like	Heals in	Typical surface	Where
Superficial	Red, dry, painful, no blisters	3-7 days	Under 5%	Home care, cool water, vet call
Partial thickness	Blisters, wet, oozing, very painful	10-21 days	5-15%	Vet same day, bandage, pain relief
Deep partial	White or mottled, less painful than it should be	21-30 days	10-20%	Vet now, possible surgery
Full thickness	Leathery, charred, no pain, hair pulls out	28-60 days to graft	Over 20%	Hospital, fluids, surgery

Use one hand as a measure: the cat's own paw pad is about 1% of its body surface, so a burn the size of 4 paw pads is roughly 4%. The whole head and neck are about 16%, the trunk about 40%, each front leg 8%, each back leg 12%, and the tail 4% in the estimate most practices use.

Chemical burns: brush the powder off first

Dry drain cleaner, lime, or pool chlorine on fur must be brushed off with a gloved hand or a stiff card for up to 5 minutes before any water touches it, because water on concentrated powder generates heat and drives the chemical deeper. After the visible powder is gone, flush for 20-30 minutes. Alkalis (pH 13-14) keep penetrating for 30-60 minutes, so they get the long flush; acids usually stop at the surface but still get 15-20 minutes. Never neutralize with vinegar or baking soda, since that reaction also produces heat. A chemical splash in the eye gets 15 minutes of flush and a same-day exam, covered in the eye injury guide.

Cord bites burn the mouth, then the lungs

An electrical burn usually shows as two small grey-white marks at the lip corners where the cat bit a live cord, and the visible wound is the least of it. Fluid builds in the lungs 12-24 hours later, so a cat that looks fine at 6 hours can be breathing 50 times a minute by midnight. Unplug the cord before you touch the cat, keep it calm, and have it examined the same day even if the mouth looks minor. A cat that fell while biting a cord needs the fall injury checks as well, because landing badly breaks the hard palate and the front legs.

Cover with damp gauze, not with ointment

• Soak 4-6 layers of gauze in saline or cool water, wring it so it does not drip, and lay it on the burn.
• Wrap loosely with a self-adhesive bandage, 1 layer, snug enough to stay but not to swell the paw.
• No toothpaste: menthol and fluoride sting and delay healing.
• No butter, oil, or petroleum jelly, which hold heat in the tissue for another 1-2 hours and trap bacteria.
• No hydrogen peroxide or alcohol on the wound; both kill the new cells the burn needs.
• No popping blisters, and no cotton wool, which leaves fibers in the raw surface.

When 20% means a hospital stay

Above 20% of body surface, a cat loses plasma into the burned tissue fast enough to go into shock within 6-12 hours, and needs intravenous fluids at roughly 2-4 ml/kg per hour for the first 24 hours plus pain control. Go in for any burn over 20%, any burn on the face, ears, paws or perineum, any burn that circles a limb, any smoke inhalation with singed whiskers or a cough, and every electrical or chemical burn. A cat with burns on 2 or more legs usually cannot be managed at home at all.

The 72 hours after: pain, infection, contracture

Burn pain peaks at 12-36 hours, and vets commonly use buprenorphine at 0.01-0.02 mg/kg or meloxicam at 0.1 mg/kg on day 1. Bandages are changed every 24-48 hours for the first 3 days, because infection shows up at 48-72 hours as a sweet smell, green discharge, or a fever over 39.5 C. Scabs that cross a joint contract over 3-4 weeks, which is why paw and elbow burns are splinted early. Fur regrows in 6-8 weeks and often comes back a different color.

Six steps in the first hour

• 1. Remove the heat source and unplug the cord before touching the cat.
• 2. Run water at 15-20 C over the burn for 10-20 minutes.
• 3. Brush off dry chemical powder before any water.
• 4. Cover with damp saline gauze and 1 loose layer of bandage.
• 5. Keep the rest of the cat warm and dry.
• 6. Call the vet for anything over 5%, or on the face, paws or mouth.
