RattyRat's Review: We've never really owned this cage, but we wanted to recommend it because it's the cheapest cage you can buy online that is suitable for two rats. This cage has some nice features. It has no wire floors, which is ideal. The bars are closely spaced together, so this cage is suitable for even baby rats. It's one level making it safe for any elderly rat, and it's easy to clean. This is a great choice if you're on a tight budget. But keep in mind, this cage is suitable for no more than two rats.
