male hognose snake not eating

i got my albino western hognose snake early in february. he has ALWAYS eaten well for me starting within the first week that i got him. but he has been growing so it got to the point where i was feeding him multiple pinkies in one meal every 4 or 5 days or so. i wanted to try to upgrade him from pinkies to fuzzies so that he didnt have to just eat 3 pinkies every meal, that and i ran out of pinkies for him. but he refuses to eat it. he has eaten one fuzzy in the last 4 or 5 weeks and thats it.

im a new snake owner so im starting to get concerned. ive tried braining the fuzzy to make it more appealing and it didnt work. i tried leaving it in his tank for a few hours and that didnt work. i tried covering his tank for privacy and that didnt work either.

is it because he wasnt ready fo fuzzies yet? or do snakes maybe get fussy after changing where i get the food from?

i originally bought the food from a vendor at the expo i got him from. he never had a problem with it. but i thought it would be simple for me to just buy his new food from a pet supply store near me and he wont eat it.

i would say maybe i should start scenting them but he has never had an issue with frozen thawed mice before. im not sure he was ever fed anything else or anything that would have been scented

i know i heard that males tend to do this i think but is there any way i can fix it? im afraid im becoming a bad snake mom 😣
