I've never heard of a cat without wrists . Do you mean she has no legs at all? Or just very short legs??
Is it possible to post a picture of her?

I have a cat with 3 legs, the 4th one is underdevelloped, caused by a per-birth-defect. Snoopy (her name) is running around like a normal cat, and climbs as high as she wants! Of course, it will always be a special needs cat; but I am most willing to give this to her!!
