I have a hypo-boa. He is 4 months old and I have had him for 2 months. During this two month period, he has had one bowel movement and has not shed at all. He was eating 1 fuzzy every 7 days, had a bowel movement after 3 weeks. Since then, I have increased his meals to 2 fuzzies every 5 days and he has not had a BM. He appears to be growing and thriving. Any suggestions?
