I have three glass snakes! I just got them about a week ago and I am wondering how often to feed them and how to know that they are hibernating and not dying? They will become active if it gets warm outside and becomes more warm inside but the last few days it has been cold and they have not come out that I have seen! I put about twelve crickets in the cage when they were all out the other day but I don't think they are any of them. How often should I clean the bedding if they are just staying in the bottom sleeping? And how often should I just get the crickets out of they haven't eat them? Any other information on them would also be greatly appreciated!
