Catit Senses 2.0 Gum Stimulators is a set of 3 replacement gum stimulators for use with the Senses 2.0 Wellness Center. Easy to replace when needed, the gum stimulator is like a cat toothbrush in disguise. While your cat is happily gnawing on the textured nub, they are actually cleaning their gums and teeth. Good cat dental care and bad breath. Entice use by adding catnip herb to the top. Catit is focused on creating cat enrichment activities for all cats especially indoor cats. Cat toys for indoor cats should encourage a cat's natural foraging and hunting behaviors. Our Catit Senses 2.0 line has created a wide variety of cat toys, with this in mind. Catit Senses 2.0 is the only cat toy series that allows you to create new and exciting setups for your cat, quickly and easily! Each toy was designed to activate and stimulate your cat's unique senses, all in one fresh, green style to match any home interior, no matter the arrangement.
