Is it normal to have a fetish with the ears of cats?

I have loved the ears of cats all my life. I like those of dogs too but not nearly as much as cats. I like to massage them, play with them, fold them back, put them in my mouth and lick them or sometimes bite them a little bit but not to hurt the cat. I do everything you can think of with them. Just the ear itself though. I do not dig down inside it or put anything in it or nothing. And I can play with the ears of cats for hours at a time. And they usually like it, or just get used to it and don't mind.

I can't explain it. And I'm really glad I though of this, because I'm so used to it I wouldn't have thought to ask it here. I have never known anyone else to ever have a fetish with the ears of cats.

(The reason I say the "ears of cats" is because I don't know if I'm supposed to say "cat's ears" or "cats' ears")
