If I am wrong, then I am wrong. Go ahead and follow the vet's advice and TRY to feed a weaned rat with medicine inside it EVERY DAY. Let me know how that works, and good luck with that. If the strategy works, I will eat my words, and apologize, if the strategy fails, call the vet back and tell them, that sure enough the snake won't eat veery day, and NOW WHAT DO I DO? I just want what is best for the snake, and I cannot foresee the snake eating a small weaned rat every day.
But what do I know? I am just alol, I hope it works, I hope the vet is right, so your snake heals. I am not a vet, so I don't know what else to do, and I am not dispensing any medical advice, I am just stating that the feeding idea sounds unrealistic, and I have fed ball pythons approximately 400 times in the last few years.people online who aren't even in the same country.
