Where can i find a fake cat skeleton?

I just Found out i draw better cats when i draw a skeleton first. I used a picture in my cat encyclopedia but thats only one pose. I want a cat skeleton thing like the human ones in some clrooms. No where, could i find a fake movable cat skeleton. Just like plastic that can be positioned. I would appreciate if it was fully movable and around $30 or under but not cheesy and falling apart.
