2. Make Cat Tooth Brushing a Regular Affair
Every day is best, but if that isn’t possible aim for multiple times a week. Schedule the brushing sessions at the same time and place every day, and make it fun. This way your cat won't consider it a chore; she may even start reminding you when it's time to whip out the cat tooth brush.
You'll want to start with baby steps, regardless of your cat's age. Start by letting your cat lick a flavored toothpaste made specifically for pets from your finger or the toothbrush, and then brush a few teeth. (Ed. note: Never use human toothpaste, as it can be toxic to your pet if allowed to ingest too much.) When you are finished with the tooth brushing session, use a cat treat as a reward for tolerating the experience. With time and practice, your cat will eventually allow you to brush her whole mouth. However, do keep in mind that you only have to brush the outside surfaces of the cat teeth. The tongue will keep the inside surfaces clean.
