I have a male boa. Both his parents are half hog island and half columbian, so I'm assuming genetically mine is 50/50 hog island, columbian? He is about 10 months old, and just a few inches over 2 ft long. He eats about 2 large mice a week, or 1 small rat a week. I was wondering, how long/big should I expect him to get, and at what rate? I know hog islands typically are a smaller species. Any information would be appreciated, thanks!
