This cage is a lovely, however the one flaw is the size of doors on the middle and bottom tier. Its in the middle and relatively small compared to the top which makes it hard to clean in the corners without taking it all apart which I'd prefer not to do. Needs more doors on the bottom two tiers I think. Top is great I can get full access to corners etc.
The trays are nice and deep as well so my guinea pigs can't throw stuff out.
