I think that is the right word. My cat was spayed about two months, but she still sticks her butt up when I scratch her. Is this anything to worry about. On a side note she sat on my lap for the first time at the weekend - yay!
Trent and Ophelia both do this. We call it "Caltitude", which I got many years ago from one of the Sniglets books (where they would make up words for common things that there weren't real words for).
