Agreed. Anecdotally, some friends had a cat that was always angry, at everyone. He never purred in his life. I said he wanted a bath. They had never bathed

Agreed. Anecdotally, some friends had a cat that was always angry, at everyone. He never purred in his life. I said he wanted a bath. They had never bathed him. They said I was insane and that he would claw my eyes out. I got into boxer shorts, started a bath, grabbed the cat. He loved it. It was the first time in his life he had ever purred. I made a friend that day. My friends were completely taken aback. I think his joints were inflamed, probably arthritis.
