TWO-IN-ONE CAT ACTIVITY TREE: Are you looking to get your pet a Cat Tree and an Exercise Wheel, but don’t have the space for both? Well, look no more! The Spin Kitty Cat Tree incorporates a sturdy, built-in exerciser wheel that’ll keep your feline friend entertained for hours! A PLACE FOR PLAYING AND TAKING CATNAPS: The Spin Kitty Cat Tree provides a comfortable space for kitties to take a nap, or play, climb, and scratch to their little hearts’ content. This versatile, 2-tiered cat tree comes with 3 removable plush resting pads. For those that seem to adventure into every little nook and cranny, the 7” hole provides a fun way to hang around. AROUND AND AROUND WE GO: When it comes to our kitties, we learn to either live with their random zoomies, or purely laugh as they skid around the floor while losing traction at high speeds! Your pet is free to run as fast as they want and for how long as they want! The 20” diameter wheel is lined with sisal carpet on both the inside and outside. The Spin Kitty Cat Tree can safely hold cats up to 15 lbs. RUNNING, SPINNING, SCRATCHING FUN: With 3 integrated sisal scratching posts and the wheel lined with sisal carpet on both sides, the Spin Kitty Cat Tree will keep your pet preoccupied and their claws away from furniture. MEASUREMENTS: Overall = 20” (W) x 35.75” (D) 35” (H) / Wheel = 20” (Dia) x 6.5” (D) / Max Weight Capacity = 15 lbs.
