Panting in Cats

Just like dogs, cats pant when they become too hot or exert themselves too much. In this situation, cats often pant and breathe quickly while keeping their mouth open.


Cats begin to breathe heavily and pant when

  • It feels too hot for them.
  • They exert themselves or are eager.
  • During a stroll or after fun.
  • They’re under pressure.

Additionally, excessive panting may be a sign of underlying medical conditions such hypertrophic cardiomyopathy, cardiac abnormalities, or lung difficulties.

What To Do:

It’s not a significant problem if your cat has begun panting after a stroll or some fun and shows no other symptoms. Whenever cats are anxious, agitated, or play in the heat for an extended period of time, they often pant and breathe quickly.
