How to Check Your Cat's Vital Signs at Home: Breathing, Pulse, Gums
Cats hide illness, so it helps to know what is normal for yours. A few simple checks at home, done when your cat is relaxed, can give early warning of heart, lung or other problems. They are not a substitute for a vet, but they can tell you when to seek one.
When to check
Choose a calm moment, ideally when your cat is asleep or resting. Do not check after play, a car trip or a stressful event, since the numbers will be higher. Practice a few times to learn your cat's baseline, and write the results down.
Resting respiratory rate
The resting or sleeping respiratory rate is one of the most useful checks, especially for cats with heart disease.
- Wait until your cat is asleep or deeply resting.
- Watch the chest rise and fall. One rise and fall is one breath.
- Count for thirty seconds, then double it. Or count for a full minute.
- Repeat on a few days and record.
Healthy cats usually take fifteen to thirty breaths a minute at rest. Many vets advise that a sleeping rate above thirty to forty breaths a minute should be reported. Rising rates over days may signal fluid in the lungs. See hypertrophic cardiomyopathy in cats and feline asthma.
Heart rate
Place your hand on the left side of the chest, just behind the elbow, and feel the heartbeat. Count beats for fifteen seconds and multiply by four. A normal resting heart rate is about 140 to 220 beats per minute, though a cat at the vet may be higher. A cat may purr, which makes it hard to feel. Wait until the cat is quiet. Note any irregular rhythm or a very slow or fast rate, and report it.
Gum color
Lift the lip gently, and look at the gums above the canine tooth.
- Healthy: pink and moist.
- Pale or white: may mean anemia, shock or blood loss.
- Blue or gray: poor oxygen, an emergency.
- Yellow: may mean liver problems or jaundice.
- Bright red: may mean heat stroke, toxin or infection.
Some cats have naturally pigmented gums, so look at the inside of the lip or eyelid.
Capillary refill time
Press a fingertip on the gum until it turns white, then release. Color should return within one to two seconds. A slower return suggests poor circulation or shock.
Hydration check
Gently pinch the skin over the shoulders and lift, then release. In a well-hydrated cat, it snaps back quickly. Skin that stays tented or slowly returns suggests dehydration, although in older or thin cats the test is less reliable. Look also for dry gums and sunken eyes. See chronic kidney disease in cats.
Temperature
A normal temperature is about 100.5 to 102.5 degrees Fahrenheit. A rectal thermometer gives the most accurate reading, but it can be stressful and risky. Ask your vet to show you before you try it. Digital ear thermometers for pets are available but may be less accurate.
Weight and body condition
Weigh your cat monthly. A baby scale or a bathroom scale (weigh yourself, then yourself holding the cat) works. Weight loss or gain can be a warning sign. See how much should I feed my cat and diabetes in cats.
Other observations
Watch eating, drinking, urination, litter box habits and energy. See signs of pain in cats and cat emergency warning signs.
Keep a log
Write dates, results and notes. Share with your vet. A phone app or a notebook works. See cat first aid kit for what to keep on hand.
Emergencies
Go to a vet right away for:
- Open-mouth breathing or panting at rest.
- Blue, gray, or very pale gums.
- Collapse or inability to stand.
- Labored breathing with the belly heaving.
- A rate above forty at rest, with other signs.
Teaching your cat to accept checks
Practice touching the chest, lifting the lip and looking at the gums as part of regular petting, with treats afterwards. A cat that is used to gentle handling will allow readings more easily, and will be calmer at the vet. Keep sessions short, and stop if your cat resists. Never force the mouth open, and do not try to measure temperature unless your vet has trained you. Pair checks with a treat, so that your cat links them with something good.
Cats with heart or lung conditions
If your cat has been diagnosed with heart disease, your vet may ask you to count the sleeping breathing rate every day or every few days and to report a rising number. Use a phone timer, record the date and number, and send results as asked. A steady rate is reassuring, while a creeping rise over several days can be an early warning that medication needs adjusting. Do the count at about the same time each day, with your cat asleep on its side or chest, to keep numbers comparable.
When to see a vet
Call your vet if a reading is outside the range or worrying. Use the US vet directory to find a clinic.
