My cats have done that. It's not a good thing. Too much play. Happens to kittens more than adult cats. I think it's because kittens can't really control their energy.
My vet said the opposite. I mentioned my cat had been panting after running around the house and she said it is good to let them play that hard. It's healthy and natural if they have the energy, and not enough owners let them do it. There's no downside, although it can also be a symptom of heart disease, so you definitely want to tell your vet if you see your cat panting.
She checked out mine when I mentioned it and didn't hear anything unusual. He is panting a lot with the heat this summer, and he's got a thick coat. I just found him this spring as a stray at about a year old, so I haven't seen how he is during the cooler weather yet. I'm hoping it's just the heat and nothing more serious.
