So you have your two adults together? I know you said you were intending on breeding in the spring, but sometimes snakes who are kept together constantly won't breed. I would consider separating them unless it's breeding season, and then cycling the male in and out of your female's cage. It puts alot of stress on snakes when they are kept together all of the time, plus, if one gets sick, then they both get sick and you have double the vet bills.
