I never used to like rats until I worked at Petco. We had accidentally gotten in a female rat with the males so we needed to keep her seperate. So we put her in a large tank with a screen on the top. Everynight she would escape, then in the morning when we opened the store and turned on the lights we would see her run around the store and go back to her cage and wait to be fed. It was so cute, she was my first rat love. Someday I'd like to get a rat, they are sweet.
