After giving me some good advice as to which cat toothpaste to buy, my veterinarian gave me the okay to begin brushing Montgomery's teeth. I brought home the toothpaste and offered him a little bit on the end of my finger. He was very interested, but he kept looking at me because he's not usually allowed to have anything but his food. When I told him he could have it, he licked my finger clean and looked for more. The next morning after breakfast, he had his teeth brushed for the first time...He sat there and purred! He's had his teeth brushed twice now and has purred both times. What a good boy!
