My wife and I just purchased 2 ball pythons. The male is 4-5 years old and the female is about 5 months old. We've had the pair for about a day now. When we've tried to pick the female up she hisses at us and he just goes under his log. I had a ball python once before but it was several years ago and I only had him for a couple months before circumstances required that I find him a new home. Just looking for some advice to help us along. Thanks.
