At six to seven months it should be near ready for fuzzies, small ones albeit. If he is too small for fuzzies you should be giving him at least two pinkies per feedingMy Milk snake is about 6-7 months old, it takes about 4 1/2 minutes to eat a pinkie, should i stay with one pinkie per week as presently or offer him another one at feeding time ?
To ingest it's food you mean. My large MBK has her adult mice down in under five minutes, my Albino Cali takes slightly longer. There isn't a timing to determine the size of prey items for your snake. Prey size is determined by the size of your snake, compared to the prey, and what its jaws can engulfIn my opinion, a snake should take 10-15 minutes to digest its food (eat it)
