I currently have a divided family. My kitty Yuki doesn't really want other bigger cats too near to her but has been progressing. She is fine as long as they keep a few feet away and don't surprise her. (Thinking this stemmed from being declawed and then thrown into the wild.) She is full grown but still a pretty tiny cat. There are two other cats who get along with each other fine in my household. I have considered getting a kitten in hopes of a companion for the younger cat, who is about 2, to play with but also for Yuki who gets restless by herself. Yuki doesn't really play currently. Hopefully I explained that well enough and included all the pertinent info. Thanks!
