I have never had an animal so instantly assimilate into the household. This morning she was really pissed at me when I told her she had to spend one more day in my office, because Bad Mommy hadn't really kitty-proofed yet. (I expected to have a longer adjustment period.) My knitting bags are entirely too accessible, for one thing. She's so far the best cat ever and not at all destructive, but still...bags of yarn...a long day of trying to keep busy.... I will deal with that and other cat temptations this weekend, because she really, really is trying to be the best cat ever, and so far is succeeding. Sophie acts like she's lived here forever. As I type this Ellie is looking out the window while Sophie snores on the rug. They are totally relaxed.
This truly couldn't have been easier, and I'm so glad I didn't really want a kitten.
