It's not safe for you to feed your snake suc a huge meal. Even if they don't regurge. If the lump stays more than 3 days it was to big. It's not a learning process a snake will eat just about anything it comes across. Be careful the next time you feed your snake. It should't be that much larger than the thickest part of your snake, or if it can't coil right then it's too big.
By any means necessary
