Title: DON'T WASTE YOUR MONEY!!!!
Review: The concept is great - but it is a crappy product and a waste of money. It is completely unstable and while the stick on velcro is very strong (and it's still on the wall - it won't come off), the dynamics of the sill doesn't make it possible for a cat to lie or even sit down on it. My cats are of medium size and when one of the stepped on it - not jumped - the whole thing came crashing down. When my husband and I tried to secure it on, we failed miserably.If you love your cat, stay away from this one.
