My name is Sherbet!

We got Sherbet from a shelter a few years ago and brought her into our home. She was very shy when we got her but hoped that with time she would come out of her shell. We had another cat at the time and while the two wouldn't fight with each other, they didn't really get along either. Sherbet remains very shy and hardly comes out for me, but she does like my roommate and will sleep on her bed or come to her for pets and attention. She is very smart and likes doing puzzles, and is food motivated. She does not like being picked up or held but loves aggressive but scratches when she comes over to you. Unfortunately we do not have the free time needed to help her fully adjust and feel bad when our other cats chase her around as they want to play with her. She has never been aggressive, bitten or scratched anyone, and I've never heard her hiss. She is just nervous and hides
