Drowning and Near-Drowning in Cats: CPR That Actually Helps

Get the cat out of the water, clear the mouth and nose, and breathe for it. Do not hang it upside down to drain the water: that burns the minutes the brain has left and lets stomach contents pour into the lungs. Give 5 rescue breaths, then chest compressions at 100 to 120 per minute with 30 compressions to 2 breaths. Even a cat that coughs, sneezes, and walks away needs a vet the same day.

The first 60 seconds

Lift the cat out with one hand under the chest and one under the rump, not by the head alone; a soaked cat is heavy and the neck is fragile. Lay it on a flat surface at your chest height, on its right side, head level with the body. Wipe the nose and mouth with a finger or a cloth and hook out any visible weed, grass, or vomit. Pull the tongue forward only if it is blocking the opening, and keep your fingers out of the back of the throat: a half-conscious cat clamps down hard.

Spend no more than 10 seconds deciding whether the cat is breathing. Watch the chest, listen at the nose, feel for air on your cheek. Breathing but unconscious means carry it to the car now, on its side, with the head a little lower than the chest so fluid and vomit drain out rather than back.

Why the upside-down trick fails

Water does not sit in the airway like water in a bottle. Most of what goes in comes straight back out, and the rest is already past the vocal cords where gravity cannot reach it. Holding a cat by the hind legs and swinging it produces a few tablespoons of water and 30 to 60 seconds of nothing while the brain goes without oxygen. It also makes vomiting likely, and vomit in the lungs is the second injury you are trying to avoid.

Rescue teaching has moved away from the swing for exactly this reason. Every second spent draining is a second not spent ventilating, and ventilation is the only intervention that changes the outcome.

Five breaths, mouth to nose

Wrap one hand around the muzzle to close the mouth, seal your mouth over both nostrils, and blow just enough to see the chest rise. For a 4 kg cat that is roughly a tablespoon of air, about 10 ml per kg of body weight. Give 5 breaths, one about every 1 to 1.5 seconds, then check for a pulse at the inside of the thigh.

If the chest does not rise, the seal is leaking or the airway is blocked. Reposition the head so the neck is straight but not bent back, check the mouth again, and try once more before moving to compressions.

Compressions: 30 to 2, 100 to 120 a minute

Keep the cat on its side. Put the heel of one hand over the widest part of the chest, just behind the shoulder blade; on a kitten, circle the chest with your thumb and fingers instead. Press down one-third to one-half of the depth of the chest, at 100 to 120 per minute, the tempo of a fast dance track. Do 30 compressions, then 2 breaths, and repeat without long pauses.

Check for breathing and a pulse every 2 minutes, and swap rescuers if someone else is there, because 2 minutes of good compressions is about all most people have. Continue until the cat breathes on its own or a vet takes over. Cats that arrive with CPR in progress have a real chance; cats that arrive 20 minutes later usually do not.

The lung damage that appears hours later

Near-drowning strips the surfactant that keeps the air sacs open and damages the capillary lining. Fluid crosses into the alveoli, so oxygen exchange falls even while the cat looks normal on the kitchen floor. Pulmonary edema and aspiration pneumonia usually show up within 12 to 24 hours, sometimes as late as 48.

Warning signs are a resting breathing rate above 40 per minute (normal is 20 to 30), coughing, foam at the nose, blue-grey gums, and a cat that will not lie down. Vets treat with oxygen, warmth, careful fluids, and X-rays on arrival plus a repeat the next day. Antibiotics are not automatic, but a cat still coughing at 24 hours needs to be seen.

Salt, water, and core temperature

Fresh water crossing into the bloodstream dilutes sodium, and in a small cat the drop can be fast enough to cause wobbling, confusion, or a seizure. Sea water does the opposite, pulling fluid into the lungs and pushing sodium up. Both patterns need blood work, and neither can be judged from how the cat looks.

Cold water also drops core temperature within minutes: a cat runs at 38.1 to 39.2 degrees Celsius, and one pulled from a winter bucket can be under 35. Below 34 the heart becomes irritable and resuscitation is far less likely to work, so warming starts in the car, not at the clinic.

Warm the cat without burning it

Towel the fur dry, wrap the body, and put the cat in a room at about 25 degrees Celsius. Warm water bottles go outside the blanket, never against skin, and get checked every 10 minutes. No hair dryer on full heat, no hot water, no radiator, no direct sun. Warm the trunk before the legs, and expect the cat to shiver for a while.

The next 48 hours

1. Keep the cat indoors, quiet, and warm, in a room at 25 degrees Celsius.
2. Count breaths while the cat sleeps, twice a day, and write the number down.
3. Offer small amounts of water and food; do not force either.
4. Go back at once for open-mouth breathing, coughing, or a rate above 40.
5. Book a recheck at 24 hours even if the cat seems fully recovered.

Breathing trouble in the first hour follows the same rules as choking and breathing trouble. Most home drownings happen in buckets and full baths, and bathing a cat covers the water depth and supervision that prevent them.
