I love this cage. I couldn't find a one story cage that wasn't C&C or unstable. I was tired of using C&C or soft bottomed cages due to leaking through the bottoms and it being really hard to clean out. I had a wood hutch for my guineas before this cage and it turned out to be a huge waste of around $300 and effort. This cage is sturdy, perfect size It fits all 4 guineas comfortably, and airy so they dont end up smelling horrible. I would highly recommend this product to any rodents other than small ones like hamsters because of course they could easily escape. But for ferrets, rabbits, Guinea pigs, and large rats a for sure yes!
