That is one of the sweetest things I've sen in a long time! The notation at the end of the video is wrong, of course, cats and dogs are not long-time enemies..... they can and do get along very well, especially when one or both are babies when they meet. The kitten was happy right away with the dog and was rubbing all over him... making him "hers" (or his...hard to tell from the video...lol).
I agree, cats and dogs can get along. I never owned a cat, but my sister did take Clinton to visit one of her friends, and that friend had a kitten. My sister said that Clinton was licking her as if he was giving her a bath! But what else did I expect, Clinton had always been a friendly and sociable dog.
