Catit® Design Senses Scratch Pad appeals to your cat's senses of touch, providing the scratching surface he instinctively needs. Cats communicate through touch. When a cat scratches an object, scent glands in the paws deposit the cat's odor as a way to mark his "territory". Add catnip or conceal treats into the cut-outs for multi-sensory appeal. Purchase the Catit Play Circuit, Massage Center and Scratch Pad (all sold separately) and create a complete Sensory Activity Center for your pet! Shipping weight: 1 3/4 lbs.
