my pairs have 2x4 cages - don't forget the depth of it is as important as the length and often varies - some of my '3 foot' cages are smaller than my others, much to my great disappointment when they were delivered :roll: I wouldn't touch Imac or ferplast cages again as they are poor quality with the door in the top too small for picking nervous piggies up (my huge Imac houses one very docile piggy - I'd fall into it trying to reach one of my 'corner huggers') and the ferplast is so hard to clean - stupid design :roll: Savic are nice, but not as deep as the others, so you may need a 5' cage by that manufacturer. Or you could buy an indoor hutch from happyhutch, as another idea - paint it how you like and use it as a sideboard - I've got several and lined the bottom and half way up the sides with fablon sticky-back plastic, so they are easy to clean
