I currently let my Chinchilla out to play in a hall way. I take his cage off the base and place it in front of one of the doorways so he cannot get out. My question is should I open his cage door to let him go inside his cage and play around or leave it closed and let him explore being outside for his play time. Hes still allowed access to his food and water because the base is still open and he can go in it. I leave it closed for now just to kind of force him to use the playtime outside his cage. Also I sometimes leave him out for an hour or two. Such thing as too much playtime outside his cage? Thanks all.
