To introduce your cat to the toothpaste, apply a small amount onto your finger and allow pet to taste. Next, apply small amount onto the Petrodex Toothbrush or Finger Toothbrush. Then, gently pull the lips and cheeks up. Begin brushing with short, back-and-forth strokes at the gum line. Brush only a few teeth the first time. Give a lot of praise during this process. Toothpaste need not be rinsed. Avoid using human toothpaste on your pet.
