Thank you both We have just the two cats... I have a feeling at least one of them will be a climber (they don't really have an opportunity to do so at the condo but I have found Espeon on top of the fridge before). Not so sure if they would play with dangly stuff... I feel like all they would do is use it as a scraching post and lounge on it... we have a scratching post for them now and they both use it all the time. They are *always* in the windows looking outside.
