Prevue Pet Products Catville Tower Gray encourages your cat to be healthy, happy and active! Watch as kitty engages in energetic activity - playing with the dangling toy, scratching the sisal covered posts or climbing in, out, over and around the Catville Tower. Cats will happily curl up in any one of the four hideaways - an elevated penthouse nook, one mid-level plus two lower-level secluded view dens, each with super-soft plush bedding to satisfy all of your cat’s sleeping needs.
