too small?

My bp is almost 20 inches long and only 90 grams or so. So far I've fed him Fuzzies and lately adult mice.

About a month ago he went through a very bad shed, and didn't eat for 2 weeks, then I decided that maybe the adult mouse was too big and fed him a fuzzy and he ate it within seconds. Then 6 days later I offered an adult mouse and he refused yet again. I'm very worried. I think he's lost quite a bit of weight. Currently he is around 90grams, maybe a bit less.

What should I do? What should I feed him? I get the fuzzies from Petco. They also have adult mice. He ate 2 of them before I skipped a meal due to shedding, and he refused another one a week later. Since then he's had only 1 fuzzy. He has refused 3 adult mice already. Should I feed 2 fuzzies during each meal for awhile? Also is it okay to feed every 5 days or so until he adds some weight?

id say go for it, as long as he gets the food. i ran out of small mice and fed fuzzies and mine ate it. The tactic i use, is if they eat 1. wait about 10 15 mins for jaw tto realign and try feeding another.
Other people may dissagree to this but it seems to work for me. Just get him eating, then wait a little for him to start wanting bigger ones.

K :) Is 90 grams underweight for a 20 inch long bp?
