Spin and Chase Cat Scratcher – An interactive toy that keeps your pet chasing, scratching, and playing this unique Scratch & Spin system features a corrugated cardboard pad in the middle and two balls they can chase in the inner track. Replaceable Cardboard Pad – Our double-sided cat scratching board can be swapped out for other round cat scratching pads for cats, so you can support active play long after this pad is torn to shreds. Perfect for supporting kittens and cats of all ages. Two Interactive Balls for Cats – Inside the track of our cat scratching pad you’ll find two smooth-rolling balls that cats will love to swat, bat back and forth, and chase, which is good for supporting both physical and mental daily health. Non-Slip Base for Stability – The Best Pet Supplies cat pad scratcher is fitted with four skid-resistant “feet” on the bottom that help keep it from sliding around on wood, tile, linoleum, or carpet, so cats can swat, scratch, pounce, and swipe safely. Durable and Contemporary Design – A small 10.25” diameter means you can easily keep this cat toy in the corner of your living area or right in the middle of the room, while the rustic, naturally-recycled wood fits seamlessly with other home decor.
