Cat health
Count the breaths while your cat is fully asleep and not purring. About 15 to 30 breaths a minute is a common resting range. If the rate stays above 30, call your veterinarian; labored or open-mouth breathing is an emergency.
One rise and fall of the chest is one breath. Count quietly for 30 seconds and double it. Stop counting and seek emergency veterinary care if your cat is struggling for air.
Wait until your cat is settled, quiet, and not purring. Watch the chest or the side of the belly without touching. One complete rise and fall counts as one breath. Count for 30 seconds and double the number for breaths per minute. If you are unsure, take another count after your cat has stayed asleep for a few minutes.
Veterinary references commonly place a sleeping or quietly resting cat around 15 to 30 breaths per minute. A single high count after play, stress, heat, dreaming, or purring can mislead you. A rate that remains above 30 while fully asleep deserves a prompt call, especially when it is new or higher than your cat's usual baseline.
A cat in trouble may pull hard with the belly, hold the elbows away from the body, stretch the neck, sit upright because lying down is uncomfortable, or breathe with the mouth open. Pale, gray, or blue gums, weakness, or collapse are also emergency signs. Call an emergency vet clinic and leave calmly; do not delay the trip to finish a count.
Write down the rate, the time, and whether your cat was asleep, purring, warm, or recently active. A short video of the chest can help if recording does not disturb your cat. Tell your veterinarian about appetite, energy, coughing, wheezing, recent illness, and any change in sleeping position instead of guessing at the cause.
Rapid breathing can have several causes, including heart, lung, pain, fever, stress, and other problems that need an examination to separate. Do not give human medicine, borrow another pet's medication, or syringe food or water unless your veterinarian directs you. Call promptly for a repeated high sleeping rate, and seek emergency care whenever breathing looks difficult.
Count one complete chest rise and fall as one breath. Count for 30 seconds while your cat is fully asleep and not purring, then multiply by two.
Do not wait on a number if your cat is breathing with an open mouth, pulling hard with the belly, stretching the neck, showing pale, gray, or blue gums, becoming weak, or collapsing.
