I have two (possibly three) huge industrial deep plastic containers. They'd be perfect for turning into bin cages and could be stacked/connected with tubes to create a larger or taller space. My question is - which animals can happily live in these? Would rats thrive in a bin cage or would they miss out on the climbing that wire cages offer? Hamsters, gerbils, mice, degus? I'm not sure at all! Obviously I won't be getting a pet just because I have a few spare tubs but I'm planning to keep an eye on our local shelter's fb pages and I'm open to giving some a home if I can provide a good enough enclosure for them Thank you!
