PetFusion's Modern Activity Cat Tree & Tower is designed for cats who love to climb and perch up high. Cats and kittens typically feel more comfortable above ground and especially love the mental and physical stimulation that goes along with getting there. This tower comes with zinc drywall anchors that attach to a wall with a hammer and screwdriver for extra stability and can be assembled in just 15-20 minutes no drilling required unless you prefer to anchor into studs or have plaster walls. Your cat will love scaling the sisal posts and perching on the cushioned pads on the platforms.
