It’s a nice spacious cage for my two Fancy Rats. They have lots of room for their toys and climbing. The construction of the cage is ok for the most part, a few pieces don’t line up well and the “ladders” have a limited placement option. The parts should be easy to clean and I am overall happy with the cage. If my rats were just a little smaller (my girls like to eat) the bar spacing would be too large. Unless you want to make some alterations like wrapping hardwire mesh around it, I wouldn’t recommend it for hamsters or mice.
