I was wondering if an adult Robo could live in a Savic Peggy cage. I have a brand new one in the shed which my Russian hamster only spent one night in and she didn't come out all night that night - she's now living happily in the habitrail ovo. It's a shame that a brand new cage is just going to waste and it would probably be bigger than the cage my Robo is in now which is the habitrail playground with an add on spaceship which he sleeps in and a loft at the other side. I'm wondering if he could get through the bars though on the Peggy cage. Anyone ever kept a dwarf hamster in a Peggy?
