PetFusion’s Modern Activity Cat Tree & Tower is designed for feline friends who love to climb. Cats 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 your wall with a hammer and screwdriver for extra stability and can be assembled in just 15-20 minutes—no drilling required unless you prefer anchor into studs or have plaster walls. Your kitty will love scaling the sisal posts and perching on the cushioned pads on the platforms!
