Stimulating and relaxing matatabi sticks for cats. The duvoplus Matatabi sticks can help reduce stress and anxiety in cats, as well as provide a feeling of euphoria. After cuddling, licking and chewing on the Matatabi stick, your cat will feel very relaxed and calm. When your cat chews on the Matatabi stick, its teeth are cleaned. This can help prevent plaque build-up. Offer the sticks up to 3 times a week to prevent habituation and put them away after your cat has finished playing with them.
