Miles and Vivienne are at the age where they are fascinated with our cats. Whenever the cats walk by, the babies cannot take their eyes off of them. They are simply enamored by our kitties. When the cats get close enough (which is not often, now that they have realized that the babies are after them), the babies reach out and grab a handful of fur and squeal in delight.
Hopefully, eventually these four (Miles, Vivienne, Noah and Chloe) will become fast friends, but I foresee a rough couple of years for our poor kitty cats.
