Maybe when she and Tito get together she will follow his example. Hopefully he won't follow hers! From what I understand sometimes it just takes a few days or weeks to get the litter box lesson figured out. I think she would also do fine in the bathroom. She is so tiny that I think she just needs a small space with the litter box nearby.
I bet Tito will become her best buddy. I can't wait for all the play pictures and stories!!
