Don't have a cat, but my friend had a cat years ago that I would watch sometimes when she went on trips. He used to lay in the bathroom sink with the faucet dripping on him. He was a Maine Coon, which is a breed that will actually swim, by choice. You can find some videos on youtube of this, lol, for real!
I have heard of the main coon for sure! Big kitties! I have never known a cat to swim though, maybe I will look that one up later. Good one!
My niece has one too, don't know if he likes water, but he will play fetch lol
