I researched just about every cage out there and finally went with this one. I couldn't have made a better choice for my little ratty girls Abbey and Hazel. I love how the whole front opens up and loads of space for toys and fun things for them to do. The cage went together without major problems, is very sturdy [...] Instructions were clear, but I would suggest labelling the pieces once you identify what's what. Also I solved the problem of the shallow bottom pan by ordering the critter nation scatter guard. They make one for the bottom and top if you have the double one, especially for this cage and ferret nation,  it's metal and safe, a great buy at a great price. Hope this helps someone.
