I had the kittens upstairs in the empty spare room to play today. They are making good progress. The male is still a little aloof but he lets me pet him. The female now rubs herself on me to get pet. She’s getting really friendly. Here are some photos.
I let Zeus in with them sometimes. He growls and hisses a lot, but doesn’t mean any harm. After spending time with the kittens, Zeus looks like a giant cat to me 😉
