That's not a bad thing! I hiss at things for ages!

Go, shit in his box, that will teach him

I erm do the same thing, I also growl like my puppy.

Do you sleep 14ish hours a day as well

That should be every mans dream, .....Here, kitty, kitty...and SHE SCORES. It sounds, like a win-win situation to me.

I hiss, curl up and purr like a cat. Growing up I acted like an animal because I thought some animals were cool and some habits stick.

Have tried liking your own balls already?

I purr when something feels good (like massages, not sexual feel good).

Oh man that reminds me of the time when I was in seventh grade and I was in the habit of hissing at things when I didn't have an answer for something or to show my dislike for something. I had no clue it was weird because my mom never told me and I weirded out all the kids. Ohhh the embarrassment.

I'm a cat person and I always do this. Just accept it and have fun with it.
