If you ever find an answer to this question, I sure would appreciate one too!! One of mine would NEVER jump up or down. Heck, she wouldn't jump out of her own way!! Now, she's learned that it's WAAAY too much fun to jump from the bed ot the chair, the couch to the table, the table to the chair, etc!!! She'll just stand in the middle of the room sometimes and just jump straight up. For no apparent reason!! I've even told her that I was going to tie her legs together. Didn't bother her in the least!! So if you figure out how to make them stop, let me know,K?
