To perform CPR on a cat, you lay the cat on its right side, compress the chest 30 times at a rate of 100 to 120 compressions per minute, then deliver 2 rescue breaths through the nose. You repeat this 30:2 cycle without stopping until the cat starts breathing on its own or you reach a veterinary clinic. The technique is straightforward, but the details matter, and knowing them ahead of time can make the difference in an emergency.
Recognizing Cardiac Arrest in a Cat
Before starting CPR, you need to confirm your cat actually needs it. CPR on a cat that is breathing and has a heartbeat can cause serious harm. Check three things quickly: consciousness, breathing, and pulse.
Call your cat’s name and gently tap or squeeze a paw. If there’s no response, watch the chest for rising and falling. You can also hold the back of your hand near the nostrils to feel for airflow. To check for a pulse, press two fingers against the inside of the upper hind leg where the thigh meets the body. This is where the femoral artery runs closest to the surface. If you feel no pulse and see no breathing after about 10 seconds of checking, begin CPR immediately.
Positioning Your Cat
Lay the cat on its right side on a firm, flat surface. A table, floor, or even a car seat will work. Soft bedding absorbs the force of compressions and makes them less effective, so avoid cushions or blankets underneath.
Pull the cat’s tongue gently forward and out to the side of the mouth. This helps keep the airway open. Take a quick look inside the mouth for any obvious obstructions like food, toys, or vomit, and clear them with your fingers if you can do so quickly.
How to Do Chest Compressions
For most cats, you’ll use one hand. Place your hand around the chest so your fingers are on one side and your thumb on the other, just behind the front legs at the widest part of the rib cage. Squeeze firmly inward, compressing the chest to about half its width. For an average-sized cat, that’s roughly half an inch to one inch of compression depth.
Compress at a rate of 100 to 120 times per minute. That’s fast, roughly two compressions per second. Let the chest fully expand between each compression. Incomplete recoil reduces blood flow, so resist the urge to keep constant pressure. Do 30 compressions in a row before pausing for breaths.
If you find it easier, you can also compress with one hand flat over the ribs while the cat lies on the hard surface. The key is consistent depth and speed. Whichever hand position lets you maintain those two things is the right one.
Giving Rescue Breaths
After 30 compressions, deliver 2 rescue breaths. Because cats are small, you can typically seal your mouth over both the nose and the mouth at once. Close the cat’s jaw gently with one hand, place your lips over the nose (and mouth if possible), and blow a small, gentle puff of air. Watch for the chest to rise. If it does, that breath was effective. If it doesn’t, reposition the head by extending the neck slightly to straighten the airway and try again.
The breaths should be small. You are inflating lungs the size of your fist, not a human chest. Over-inflation can push air into the stomach or damage lung tissue. A gentle puff lasting about one second is enough. Deliver the second breath immediately after the first, then go right back to compressions.
The Full CPR Cycle
The pattern is simple: 30 compressions, 2 breaths, repeat. Do not stop to check for a pulse between every cycle. Interruptions in compressions reduce the chance of restarting the heart. Instead, check for signs of recovery (breathing, movement, a palpable pulse) every 2 minutes, which works out to roughly every 5 cycles.
If you have a second person available, one of you should call the nearest emergency veterinary clinic while the other starts CPR. Ideally, you switch roles on compressions every 2 minutes. Effective compressions are physically tiring, and fatigue causes people to compress less deeply without realizing it. If you’re alone, do CPR for 2 minutes before briefly pausing to call the vet, then resume immediately.
Continue CPR during transport to the vet if at all possible. Having someone perform compressions in the back seat while another person drives is far better than stopping CPR for a 15-minute car ride.
Common Mistakes to Avoid
The most common error is compressing too slowly or too shallowly. People tend to be cautious because cats feel fragile, but compressions that don’t reach half the chest width won’t generate enough blood flow to matter. Yes, there is a risk of rib injury. But a cat in cardiac arrest will die without compressions, and a cracked rib is survivable.
Another frequent mistake is spending too long checking for a heartbeat before starting. Cats can be difficult to assess, especially under stress. If you’re unsure whether there’s a pulse after 10 seconds, start CPR. The risk of doing compressions on a cat that doesn’t need them is far lower than the risk of waiting too long to start on one that does.
Blowing too hard during rescue breaths is also common. Think of it as a puff, not a full exhale. And don’t tilt the head back as dramatically as you would for a human. A gentle extension of the neck is enough to open a cat’s airway.
What to Expect Realistically
CPR is worth doing, but it’s important to know the odds. In a study of over 200 dogs and cats that received CPR at a veterinary hospital, 46% initially regained a heartbeat, but only about 10% survived to go home. Cats, interestingly, had significantly better odds than dogs, with nearly five times the likelihood of surviving to discharge.
Those numbers come from a hospital setting with veterinary professionals, medications, and monitoring equipment. At home, without those resources, the chances are lower. That doesn’t mean you shouldn’t try. It means the goal of at-home CPR is to keep blood and oxygen circulating until professional help takes over. Every minute of effective compressions buys time.
After Your Cat Starts Breathing Again
If your cat regains a pulse and starts breathing, do not assume the crisis is over. Cardiac arrest causes widespread oxygen deprivation, and the hours that follow are critical. Keep your cat warm (wrap in a towel, avoid heating pads that could burn), minimize handling, and get to a veterinary emergency clinic as quickly as possible.
At the clinic, your cat will need close monitoring for complications including low blood pressure, neurological problems, and further heart rhythm disturbances. Seizures can occur after resuscitation, and body temperature needs to be brought back to normal gradually. Post-arrest care is intensive, but cats that make it through the first 24 hours have a reasonable chance of meaningful recovery.
