I feel like I'm making my rats miserable, and they would be so much happier in another home.

I have a big cage for them, tons of boxes and shit for them to run around in inside their cage...I give them treats, I take them out and cuddle/scritch them...but that's all I do. I don't really do any other activities with them other than simply holding them and cuddling with them and shit.

I can't let them run around in the house somewhere, we can't really rat-proof any rooms. I don't have any of the more elaborate toys like "digging boxes" or anything, just lots of boxes and tubes. They had an exercise wheel but they outgrew it, so we're getting them another one of those...

They seem happy enough, but do you think they have enough? I feel like I'm holding the poor little things back even though I love them ;_;
