It’s a really good idea to brush your dog’s teeth every day to prevent plaque and tartar build-up. Veterinarians suggest cleaning a cat’s teeth regularly too. Here’s is a useful tip if you cat is not very co-operative. Take a Q-tip and dip it in tuna juice and rub is along the teeth and gums. If you cat doesn’t let you work your way completely around the mouth, do it in stages over a couple of days.
