Cats don’t like people touching their pearly whites. Your cat may be reluctant to let you in on the fact that cat dental treatments are sufficient to keep Kitty’s smile healthy. Plaque buildup eventually becomes tartar which can cause pain and even loss of teeth. Regular brushing of your cat’s teeth, at least once a week, is the best way to keep Kitty’s gums healthy. It will also help reduce the need for expensive professional dental cleanings.
