I love our cat condo, and so does our Tobie .  Especially the top, he can look out the deck door, and watch birds , and then will put his condo in the screen porch when it is warm and he really can get a good look.  He is a  Blue Seal mitted Ragdoll, with light Blue eyes. almost 2 years old and very active and funny,  He is where ever we are, and can keep his eye on us .  right now he is on my desk watching me type... my husband has had allot of health problem' this last month and is so much company for him.  He is dusting my keyboard with his tail now, and we are from the ice Box of the Nation , Int'l Fallls, MN with Canada across the river. Also our Condo is strong when he jumps up, and it isn't tippy at all.
