I really like this cage, it seems nice, and roomy. I currently have two rats but I would like to get at least a third, maybe even a fourth.

Do you think that cage would be suitable for 2-4 rats?

It seems nice and sturdy and I like the fact that it has the little storage type area underneath it...what do y'all think?
Before I got my two rats, Tiny and Remy, I had never had rats before so I didn't realize how bored they would get with the cage the pet store told me to get, it is really tiny and with the house, food and water things and the litter box, well it is just a tight squeeze and today I bought them a hammock and tunnel and I got home only to realize there really isn't enough room! lol
