I brought them in a week or so ago when we had a lot of snow coming and it was cold. I am not sure how happy they are being in their inside cage as they spend most of their time hiding. I have also noticed funny little coughing/choking sounding noises that are different from their squeaks.
I don't know if they can go back out and if they need a vet and would appreciate any advice. My guide books don't help.
