Happy New Year everyone! I will be ordering a new cage next week and its down to two almost identical cages. I have decided on the 80x40 double over the 64x32 double. The HQ cage is 4 inches taller but besides that I don't have any idea the differences between the two brands. This is for a male GW who is finally getting his house upgraded, until we have space for a walk in. Any opinions or preferences between the two brands or cages would be greatly appreciated. Thanks!
