Query: One trick in this book is dangerous to your cat

Caution: One trick in this book is physically dangerous to your cat. Our vet said it is dangerous for a cat to stand-up on their back legs. Their hind legs can not support this activity. You will injure your cat. Please stop this trick. There are many, many other tricks cats can learn & not hurt themselves over time. PS Dog's hind legs can support standing-up - just not cats legs.
