After just buying a brand new 4ft hutch for my two boys, it seems that they are still going to be coming indoors early evening, so I'm now looking for a new indoor cage as the one I got given with them is only a ferplast 80 (yes far too small) but I give them the run of my kitchen. This isn't practical as I have a very inquisitive Yorkshire Terrier, so CnC cages are out of the question too. Are double indoor cages any good, or should I go for a 120 or some sorts?
