Is it true they tend to ruin all furniture and they jump way higher than the other cats ?
I have no idea but what I have heard about ragdolls is that they are very "limp" cats. In the sense that you can do anything you want to it and it wont scratch. They are good for households with children. but then i could be wrong as this is what i have heard only.
I have never heard of ragdoll cats. i personally think that any cat can mess up your furniture if they wanted to. that's the way cats seem to be.
