so i have two young boys. i want to get them a bigger cage, and i might be looking into getting them neutered and getting a girl within the next few months. does anyone have any suggestions for an inexpensive cage that would fit three full grown rats?
I would check ebay or craigslist, and then plug the dimensions of a cage you find on there into a cage calculator. A lot of cages might require putting up hardware cloth, since the bar spacing is too wide for rats (this would be a problem for most females, or a small male). You could also build your own cage if you don't find anything that you really like.
