Q. My cat is breathing a little faster than usual - about 35 breaths per min, slowing to around 28 when dozing. No other symptoms. He's 12 y/o.
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. Normal sleeping respiratory rate for cats is under 30 breaths per minute, so while technically what you're noting in your cat is normal, it's pretty high. If you're appreciating that he's breathing abnormally, there's likely a problem. I'd recommend getting him checked out by your vet to rule out serious respiratory problems, like asthma, and heart disease.
