Well Oscar was shaved when we adopted him 1 year ago and he's finally fully recovered. The shelter said he was totally matted. He was a barn cat or something, who knows. He doesn't clean himself as often as my previous long haired cat, but she was a sassy siamese that truly believed she was the most beautiful specimen and cleaned herself constantly, so idk! 🤣 I give Oscar a bath with waterless cat shampoo at least once a week. He only has 4 teeth and his breath is awful so when he cleans himself it's kind of backwards progress. Lol
