One of the most well-known manufacturers of cat dental treats is Greenies, and their Feline Greenies Dental Treats are designed just for cats. The crunchy texture of these dental treats for cats' sweets is intended to lower tartar levels (and that cats will love biting into). Having a fallback strategy is wise in case something goes wrong. They won't replace regular dental cat treats, but they can assist in maintaining your pet's oral health in between veterinary appointments and at-home cleanings.
