Thanks everyone for the responses! I've looked at Martin's but didn't really know if I wanted a cage from there, as I want solid floors. Right now their cage bar spacing is 7/8" so I know the two cages I narrowed it down to would work. I also looked at ferret nation, but I kind of want to stick with super pet as their brand has worked for me so far. I kind of wonder if the first cage is almost too much space, but I like how I could fit so many toys in. I like the second too, but don't really like how there's not that much floor space. I don't know, this is a hard decision!

Christmas Hamster: Would a 12" wheel look awkward in the second cage, the one you have? And also how many doors are there?
