cat♪

I found this movie at YouTube, the title is maru's forefoot. Whenever she do a jump, she fold up her forefoot! It is very very cute!! I want to watch her real jump!I didn't know the cat's behavior like this. Does every cat have this behavior? I want to know truth. If you know the answer, please write a comment.
I will observe my grandparent’s cats when I go to their house next week. But it will difficult, because they often run away when I try to close to them :-(　　[92/9881]
