Just please remember what I mentioned to you last time and mentioned again below, Blaze may not fit into the next mouse size in just 6 feedings, so you need to get the digital scale to know if he should move up in mouse size based on his weight and based on not regurging and not having abnormal poop/urates. As well I am not an expert or a vet and if this was my snake as I have said several times before, I would be getting any vet, reptile or not to at least do a fecal float for parasites etc, esp. with the history of regurges, abnormal poop/urates and lack of growth.
1) Start with the smallest pinkie head, just buy the pinkies and freeze them, PLEASE do this for at least 4 meals, spaced 7 days apart.
2) Then move to half the bodies you put back in the freezer, for the next 4 feedings, spaced 7 days apart.
3) Then when you move to the whole pink, you could try cutting it in half(while frozen) then thawing in a ziploc bag, so that Blaze has two small pieces to eat, giving him the whole pinkie but in a much easier to digest form(like carnivorouszoo suggested) I did this with my wee one when he regurged and I was moving him back up slowly. Do that for 4 feeds, spaced 7 days apart.
4) Then move to 4-6 meals of the smallest whole pinkies( to see how he does on those, before you moved up) spaced 7 days apart
5) Then move to 6 meals of 1.5 of the smallest pinkies spaced 7 days apart
6) Then move to 6 meals of 2 of the smallest pinkies spaced 7 days apart
7) Then move to the smallest peach fuzzy, this is a fuzzy that is just getting a thin coating of hair should only weigh about 5 grams, 6 meals of these spaced 7 days apart
8) Then move to regular fuzzies, about 7 grams, 6 meals spaced 7 days apart
9) Then move to small hoppers, about 9 grams, 6 meals spaced 7 days apart
10) Then move to regular hoppers, about 11 grams, 6 meals spaced 7 days apart
11) Then weanlings about 13 grams, 6 meals spaced 7 days apart
12) Then weanlings about 15-16 grams, 6 meals spaced 7 days apart
13) Then sub- adults about 17-18 grams, 6 meals spaced 7 days apart
14) Then adults about 20 grams, 6 meals spaced 7 days apart
This all is only good IF he does not regurge again OR IF his poops do not continue to look as they have. As well you need to get a digital scale that weighs in 1 gm or less increments so that you can know if he is gaining, loosing or maintaining his weight.
Plus as I mentioned before it lets you know if he gains enough weight to fit into the categories listed in the Munson Plan I gave you below. I say this because this snake needs very slow and steady. If it takes more than 6 meals to get to a new weight category that suggests the next size of mouse than do not move up until your snake weighs the minimum weight in that category. AND if your snake gets to a weight before the 6 meals are fed DO NOT move up until he has had the 6 meals at the smaller size and kept them down!
The Munson Plan (Sample Feeding Chart): Revised 06/08/08
For this you will need a digital weigh scale that will weigh in 1 grams increments or less.
-When they're on single pinks (2-3g), I feed every 5-6 days. (Snake = 4-15g)
-Double pinks (3g x 2) every 5-6 days. (Snake = 16-23g)
-Small fuzzies (5-7g) every 6-7 days. (Snake = 24-30g)
-Regular fuzzies (7-9g) every 6-7 days (Snake = 30-50g)
-Hoppers (9-12g) every 6-7 days (Snake = 51-90g)
-Weaned (14-20g) every 7 days (Snake = 91-170g)
-Adult (20-30g) every 7-x days (Snake = 170+) See below.
Note: Adult females are fed more frequently than adult males (especially following brumation). Adult females are fed every 7-12 days; adult males are fed every 11-14 days.
