A scald is decided in the first 10 minutes: get the cat under cool running water within 10 minutes, keep the water running for 15 minutes, and put nothing else on the skin. No toothpaste, no butter or oil, no ice, no alcohol, no iodine. Any burn larger than 1 percent of the body surface, or one on the face, mouth, paw pads or belly, needs a vet the same day even if the cat seems fine.
Why the clock, not the cream, sets the outcome
Skin keeps cooking after the heat source is gone. Protein in the dermis denatures for several minutes after contact, so a burn that looks like a pink stripe at minute 1 can be a full-thickness patch at minute 30. Cooling inside the first 10 minutes slows that spread and cuts both pain and swelling. Water at 15 to 20 C is the working temperature. Ice at 0 to 4 C constricts the small vessels that carry heat away, and a soaked 4 kg cat loses 1 to 2 C of body heat in 5 minutes, a second emergency on top of the first.
Ten minutes of water, counted properly
Turn the tap on before you lift the cat and test the stream on your inner wrist for 3 seconds. Run water over the burn, not over the whole animal: a 4 kg cat soaked head to tail loses heat faster than the burn gains from cooling. Ten minutes is the floor for a splash under 2 cm; 15 minutes for anything on a limb, a flank or a paw. Do not fill a sink and dunk the cat, because standing water drifts to 25 to 30 C within 2 minutes and stops working. If the cat shivers, goes limp, or the gums look pale, stop at 10 minutes, dry the body, and drive to the clinic with the burn still uncovered.
Size the burn in palms before you phone anyone
Use the cat's own front paw pad as 1 percent of its body surface: the flat of the pad, not the toes. One pad is 1 percent, 4 pads is 4 percent, and 15 percent is where most vets start talking about shock, intravenous fluids and a 48 hour stay. A kitten under 6 months carries roughly double to triple the surface area per kilogram of an adult, so the same splash of hot oil covers 2 to 3 times the percentage. Measure with the kitten's pad, never with your own palm.
| Burn size | Paw pads | Percent of surface | Seen within |
|---|---|---|---|
| Coin-sized splash | 1 | 1% | 24 hours |
| One limb or flank patch | 2 to 3 | 2 to 3% | 6 hours |
| Belly plus inner thigh | 4 to 5 | 4 to 5% | 2 hours |
| Two limbs and chest | 8 to 10 | 8 to 10% | 1 hour |
| Back, both flanks, or over 10 pads | 10 or more | 10% or more | Immediately |
Depth: read the surface again at 2 hours
Superficial burns are red, painful and slightly swollen, with no blisters, and they close in 3 to 7 days. Partial-thickness burns blister, look wet, and the hair pulls out with the skin; they take 10 to 21 days and often scar. Full-thickness burns are white, gray or leathery and oddly painless, because the nerve endings are gone; those need surgery and a specialist, not a dressing. A burn can deepen during the first 24 to 48 hours, so the 2 hour look is a first reading, not a verdict.
What never goes on a burn
- Toothpaste: menthol feels cool for 30 seconds, then traps heat under a film and hides the depth from the vet who sees the cat 6 hours later.
- Butter, oil, petroleum jelly: they hold heat in the tissue and seal in bacteria, and every one of them has to be scrubbed off before the wound can be assessed.
- Ice or frozen peas: 0 to 4 C narrows the vessels, deepens the injury and pushes a small cat toward hypothermia.
- Alcohol, hydrogen peroxide, iodine: all three kill the cells that are trying to resurface the burn, and peroxide also bubbles dirt deeper into the wound.
- Cotton wool and tight bandages: fibres stick to the raw surface, and a bandage that is snug at minute 20 is cutting off a swollen paw at minute 120.
The first 24 hours, hour by hour
| Time after the burn | What you do | Numbers to check | Call the vet if |
|---|---|---|---|
| 0 to 10 minutes | Cool water 15 to 20 C for 10 minutes | water 15 to 20 C | flame, chemical or electrical cause |
| 30 minutes | Pat dry, cover with a non-stick pad | temperature 38.1 to 39.2 C | shivering or pale gums |
| 2 hours | First honest look at color and blisters | area in pads and percent | over 2 cm, or face, mouth or paw |
| 6 hours | Check swelling, drinking, litter box | water 30 to 50 ml per kg per day | no urine in 12 hours, vomiting |
| 24 hours | Re-check depth and weight | weight loss above 5 percent | black or white leathery skin, fever above 39.5 C |
Burns that are an emergency, not a wait-and-see
Drive for any burn over 15 to 20 percent of the surface, any burn on the muzzle, lips, eyelids or airway, and any burn across all four paw pads, because a cat that cannot put its feet down stops eating within 24 hours. Chemical burns get 20 minutes of water first, then a poison control call; plant sap, drain cleaner and battery acid keep burning until diluted, and the toxicity tool sorts chemical injury from plain contact irritation. Electrical burns, burns that circle a limb, and any burn on a kitten under 8 weeks go in at once.
Dressing changes and the 7 day check
Cover the burn with a non-stick pad held by self-adhesive wrap, snug enough to stay on and loose enough to slide a finger under. Change it every 24 to 48 hours, or at once if it smells, seeps through, or the cat starts licking. Rinse with lukewarm saline, not antiseptic. A cone stops the 4 am licking that turns a healing burn into an infected one. Partial-thickness burns get rechecks at 48 hours and 7 days; one still open at 21 days needs a grafting opinion. Scars contract for 6 to 8 weeks, so a limb burn needs a range-of-motion check at every visit. Hot water scalds differ from flame burns in how fast the depth advances, while the wider burn protocol keeps the same clock.
Five steps for the next hour
- Water on within 10 minutes, 15 to 20 C, for 15 minutes, on the burn only.
- Dry the rest of the body and keep the room at 22 to 24 C while you cool the patch.
- Photograph the burn next to a coin for scale, so the 6 hour comparison is honest.
- Cover with a non-stick pad, add a cone, and offer water but no food for 2 hours.
- Call the clinic with three numbers: percent of surface, time of injury, and cause.
Frequently asked
How long do I run water on a cat burn?
Fifteen minutes at 15 to 20 C, started inside the first 10 minutes after the injury, is the standard most vets give. Ten minutes is the floor for a splash under 2 cm, and longer cooling adds little after 20 minutes while pushing a small cat toward hypothermia. Keep the rest of the body dry and warm while you work.
Can I put toothpaste or aloe on a burn?
Neither. Toothpaste traps heat under a film and hides the depth of the burn from the vet, and aloe gels are not sterile and sting an open wound. Butter, oil, ice, alcohol and iodine are all worse. A non-stick pad held on with self-adhesive wrap is the only thing that belongs on the skin before an exam.
How do I know if a cat burn is serious?
Measure with the cat's front paw pad, counting 1 pad as 1 percent of body surface. Over 10 pads, any burn on the face, mouth, eyelids or all four paw pads, and any burn that is white or leathery instead of red needs a vet the same day. Kittens under 8 weeks go in for any burn at all.
