It would be a toss up for me. Sleep anytime does sound good. I am also a klutz and very inflexible, having the flexibility and the grace of a cat sounds good too.
and,For me it would be the "petting". Can you imagine how nice it would be to get massaged for endless hours of the day? Odie and Garfield are my little babies at 7 weeks old and lay on me to sleep for hours at a time and I always find myself petting them while they sleep.
Oh, gosh. It's a tough call between sleep, or not having to do a darned thing I don't want to do.
Actually I saw the speutering as an advantage. No need to worry about birth control any more.What's not to like about being a cat (except the speutering)?
