ganime,
Noah doesn't usually like other cats either. He growls a bit, but for some reason, he really took to Basil. It's strange, but a good thing!

I think that they generally get used to the other cats though. Noel is still intrigued by Basil...she wants to play with him...but she has her pride. I think eventually she'll play with him too. She is already sleeping in his bed/dome thingy when he's out of his room.
