Hi I’m in the uk where at the moment it’s colder than normal. My two Russians Alice and Charlie are housed outside in an insulated heated small shed. They have a wooden portion between them with their own heat bulbs a strip light between them. I’m not hibernating them, this last week while we’ve had low temperatures and snow Alice has been scratching a lot !! I open her hatch door and she went out which surprised me. I did post a photo. Anyway since that day she just wants to go outside in the cold, she will go inside for a warm on her own then outside again. I’ve noticed she’s not eating much at all either. Has anyone any ideas , is she trying to hibernate maybe? She is 6 yrs old and weighs nearly 1000 grms Charlie on the other hand is still eating maybe less than normal I put that down to time of the year , but doesn’t show any interest for venturing outside.
