hmm won't eat thawed eh.

did you do the ratty dance? using forceps you grab the rat behind its front legs and simulate a live prey for the snake to be fooled by.

another method is scenting enclosure before introducing prey item. some rat or mouse bedding in the tank to get your python in feed mode so once the rat is introduced the snake will go for it.

another method of coaxing your snake to accepting thawed rodents is to prekill so its more fresh smelling to the snake

someone will offer better more hands on advice since i feed live
