Thanks for the tips JoyjoyMarie and from everyone else. I have been playing with her with a strip of flannel. She will play for a few minutes then loses interest. Her mother was a feral but I think at one time she must have been tame. The person I got them from said the mother tamed up quickly. The kittens were feral for about four months. Mischief acts like she wants to get closer but will run when I try to pet her. She keeps getting closer to me when I'm on the sofa. I think Fluffy, her sister, is part of the problem too. She is a very vocal cat and has a very loud meow that sounds like she's saying "hello".
I've been using Kitten Attract litter. It's supposed to be guaranteed no accidents. It didn't work with Mischief. I just changed one box to Tidy Cats to see if that would help. One box is covered the other is open.
