"Cats groom each other as a form of social bonding. There's also evidence to suggest that cats view and treat their human captors as large cats. As a human, you're left out of the intimate licking ritual. At best, you have a one-sided licking relationship with your cat.
We have designed LICKI brush to bring you and your cat closer. By using LICKI with your cat on a regular basis, you'll develop a more intimate and bonded relationship, much like a mama cat bonds with her young."
