Our cage is in the living room, one side opens up in to the garden and the other in to the living room. They have full access to the garden and downstairs in our house, plenty to eat and lots of toys. They still chew on the bars when the cage is open so I don't feel guilty anymore :roll: I've noticed that they tend to chew at the corners rather than the doors at the front so I think they're just trying to extend their space like when they dig up the garden
