Yeah, that is what I figured. I remember when I had my cats, I had one girl and one boy. Misty (the girl) seemed to take more time to bounce back than Amadeus (the boy). They kept Misty a bit longer for extra observation, but Amadeus got to come home the very next morning, and he was fine. She laid around for a couple days. It makes sense if you think about the anatomy, I guess.
geeze I miss those cats
