I had a kitten once who was terrified of water. If I took a bath, the cat would get up on the ledge of the tub, take hold of my arm with his mouth, and try to pull me out.
I guess he thought I was insane to be in there.
Sometimes, Cats can be as openly protective of their owners as Dogs. Not always the detached and passive, observer.
I guess he thought:
“There’s no need to fear, the Cat Calvary is here!”
