Is my senior cat's rapid breathing and murmur a sign of CHF?

Updated On September 23rd, 2025

Pet's info: Cat | Maine Coon | Female | spayed | 6 lbs

Wrigley is eating well and has a ravenous appetite at night, but I'm noticing that she has shortness of breath, sniffles, and rapid respirations at times. Her resp. rate will go from 60 to 20 when she goes from being active and walking around, to laying on the bed. She can't seem to get comfortable and won't lay in one spot for long. She jumps up and gets startled when sleeping and does have a grade 3 murmur. Her purring is getting more forceful and louder. Is this CHF? She is 20.

Increased respiratory rate can be a sign of congestive heart failure and it sounds like you should have your vet examine Wriggy soon. Thyroid disease is also common in older cats and can cause an increased heart rate and ravenous appetite typically along with weight loss.
