Right now they are still with their Mom at my friend's house. I was outside so I took the photos through the window. I will see how the others react when they come home. But with Albie and Bubbles I just let them into the same space straight away and Albie made friend with Snerd on his first day. Bubbles was so traumatized by his old home it took him a week to settle, but that was humans rather than the other cats. Star was growling at first but they adjusted really quickly. Hoping for the same with the kittens.
