My boy cat does it when he's been running about. I took him to the vet because he's a bengal and bengals can be more likely to have HCM (a heart condition). The vet listened to his heart and said he sounded absolutely fine and that he was probably puffed out from playing. Since then I've enclosed my garden so he can play outside as well as in and he pants much less despite running around more so I'm guessing like humans, the more exercise they get the less likely they are to be puffed out easily!

We have a four month old kitten, and he pants too. Up until now, the only time I saw cats pant was when we took our cats to Saudi Arabia with us, and obviously they found it very hot and hence the panting now and again. But I had never seen a cat/kitten in the UK panting. He tends to do this after exertion, whether it is chasing toys, or attacking our older cat which he takes great pleasure in, much to her disgust. He seems to get very wound up at these times, so maybe it is a stress thing. He is due to be castrated in just over a week, so I think it is worth getting checked out. I am at the vets with my older cat tomorrow, so will mention it then.

My kitten pants when she's been bombing around-she only usually does it for a few seconds. I mentioned it to the vets twice, once when I first noticed it and again when she went to be spayed, both times I was told it's nothing to worry about.

I am sure it is nothing to worry about. He has already been panting this morning too.
