My Cats Keep Following Me Into The Bathroom

I just had to reply to this post because one of my cats is actually a bathroom sitter. He stays in the bathroom most all day and either lays on the toilet seat or on the side of the bathtub. I think he just waits for me to use the bathroom. When I sit down on the toilet to go, he jumps on my lap and purrs and when I am done, I have to tell him to get up.

I don't know what his fascination is with the bathroom, but he seems very content hanging out in there. He leaves to eat and use the litter box, but then he goes right back.
