Is it weird to get turned on think about being a cat ?

Only if te think it is. Otherwise, te are te and will feel how te feel. I've been learned that everyone is unique and it's not up to me to judge you.

Everyone has their fetishes. I have mine. (I am not inclined to tell them at this moment but I have unique ones) As long as you're not trying to hurt people (exception is bdsm) o yourself. I don't really judge often at all and this fetish while unique isn't a bad one. Have più confidence in what te like/dislike.
