Petlinks Dream Curl offers multi-surface scratch satisfaction for your cat with both sisal and carpet surfaces. The curved angles provide faux further stimulation and also provide rest and hang-out nooks for your kitty. An attached catnip toy offers fun and entertainment with potent, pesticide-free catnip. Most cats respond to catnip with a burst of energetic activity followed by a purrfectly calm mellow period. Our catnip is produced without chemicals or pesticides and is grown on our own catnip farms. The instinct to scratch is hard-wired into cats, they scratch to mark territory and promote healthy nail growth as well as stretch and tone muscles and even alleviate stress.
