I picked up a 7 month old ball python about 10 days ago, and the owners had only been feeding him small pinkies once a week. Now from what I've read on here that seems a bit small for a growing baby. I offered him a pinkie after he had been left alone for 5 days, and he took it without any problems. His neck is only about as big around as a pencil, but the widest part of his body is just slightly smaller than a small mouse. Would it be alright to make the jump to small mice when it's feeding time, or should I try keep him on pinkies only offered more frequently?
