Normal Cat Breathing Rate. Cats whose heart rates fall closer to 140 beats per minute are often felines with a more relaxed and easy going demeanor. A relaxed cat will measure on the lower end of the scale.
It will normally settle down after a short period of time. Respiratory rate is another key vital that you should be familiar with in your pets. Be concerned if your cat’s breathing is abnormal.
It's like he's a perfectly normal cat except he breathes rapidly.
If your cat cannot breathe properly, make sure to take it to the vet immediately as its life could be at risk. Any other time, breathing can be confused with purring or breathing can be faster from activity. When is rapid breathing normal? Count the number of breaths your pet takes in 1 minute.
