This sturdy pen turned out to be very useful for me. I have two female rats, one who comes when called and the other who doesnt. The one who doesnt is also fatter and cant climb out of this pen, although the other girl can. I guess its mainly a ferret pen so I wasnt sure if it would work for the ratties, but in my particular situation it works great. The bars are too close together for the girls to either slip through or get their heads stuck. All in all I would recommend this both as a playpen for ferrets OR rats, especially if your rats are on the large, fat side! :)
