i was told that my garter is not eating because of the winter times so i should brumate him for a month or so. just to get his appetite back. what im going to do it turn off her light for a week to make some difference, then put her down stairs for some time. i dont know how cold it is because i dont have a thermometer to check temps but downstairs is pretty cold compared to my room.i think the temps are in the low 60's. is that ok for a short brumation? or does it have to be colder? what temps do i have to have it to brumate?
