Checking Your Cat's Vital Signs at Home

In this guide

Cats are remarkably skilled at hiding illness, which makes knowing their normal vital signs genuinely useful, since it becomes far easier to spot what is not normal. Few cat owners could confidently answer a quiz on normal temperature, heart rate, or respiratory rate, but the good news is that all three are simple to learn and check at home.

Taking Your Cat's Temperature

An ear thermometer designed for pets is the easiest option. A traditional glass thermometer, or a digital rectal thermometer that beeps once ready, also works well. For a rectal reading, lubricate the thermometer with a water-based lubricant and gently insert it about one to two inches into the rectum, never forcing it. Leave it in place for two minutes, or until the digital beep sounds, then read and note the result. A healthy cat's temperature normally falls between 100 and 102.5 degrees Fahrenheit, roughly 37.8 to 39.2 degrees Celsius. Call the vet if the reading comes in below 99 degrees or above 103 degrees, or if there is any blood, diarrhoea, or a black, tarry residue on the thermometer.

Taking Your Cat's Heart Rate

Using a watch, stopwatch, or phone, feel for the heartbeat with a hand placed over the cat's left side, just behind the front leg. Count the beats over fifteen seconds and multiply by four to get a reading in beats per minute. A normal heart rate sits between 140 and 220 beats per minute, with relaxed cats measuring toward the lower end. A rate that seems too fast, too slow, or irregular is worth a call to the vet.

Taking Your Cat's Respiratory Rate

Watch a relaxed, standing cat breathe, focusing on the movement of the chest and abdomen. Count the movements over a full sixty seconds, since breathing is too slow to reliably count over fifteen seconds and multiply. A normal rate falls between 20 and 30 breaths per minute, again with relaxed cats sitting toward the lower end. A rate that seems too rapid, or a cat that is panting, which is not typical cat behaviour the way it is for dogs, should prompt a call to the vet.

Practice Makes It Easier

Learning these checks before a cat becomes unwell, while both owner and cat are relaxed, makes it far easier to act quickly if a genuine concern arises later. A vet can demonstrate the technique during a routine wellness exam if extra guidance is needed.
