I'm thinking about buying a cage from ferret nation http://www.ferret.com/itemdy00.asp?T1=630503&Category=Ferret Cages&subCategory=See All Ferret Cages and I put the mesurement in the rat calculator and it said it could hold 14 rats! Do you think thats true? I've never seen one in person but it must be big!! But I might be crazy i don't know...lol...but I'm wanting it to put my 3 girls in and my 3 boys. It says that the ladder folds up so it could have 2 different levels... so just to be clear THE BOYS AND GIRLS WILL NOT BE TOGETHER!.....I might even be putting the mesurments in wrong... I have never got good grades in math...lol...because i just did it again and it said 16 rats... so im confused
