Our cat trees all have removable zippered fleece beds that are soooooo comfy but can also go in the washer and dryer if need be . . .
The are the finest available anywhere and custom built and factory direct from our good friend Wolfgang ! They go from mild to WILD . . . . our Spoiled Babies really like the smaller ones named Aunt Bea's Mayberry Lodge it has a sturdy play box with two sisal columns with both a sleeper and a hammock. They have been using their cat tree since they were about 6 week old - there is one in my bathroom and Mom likes the top sleeper when wants to be by herself.
