My tabby girl loves her food and doesn't like to go outside too much. She is 3 and a half but only little. She does love chasing feather toys inside but I have noticed that after a while she flops down and starts breathing heavily. Not panting, just fairly rapid chest movements.
Could this just be a sign of being a bit unfit? Or do you think it warrants a visit to the vets?
She is otherwise in good health and seems to be very content with life in general.
