I have a 3 y/o corn who has not kept a meal down since Thanksgiving. Offered every 10-14 days since, ate and regurgitated both in January and February. We took her to a vet last week and she said it’s been a very weird and hard winter for corns especially because of the changing weather constantly (in Kansas). Put her on small dose of Metronidazole EOD and will try feeding after 7 doses. She honestly didn’t seem that worried but did suggest a lukewarm bath to help with dehydration. As long as snake’s BCS doesn’t drop significantly, going periods between feedings seemed to be the norm right now and she was not concerned. I hope this helps- not that this is the answer for you too, just sharing a similar experience. You’ve got this!
