<3 thank you friend. your words were helpful.I don't have a corn and I don't have a clue what is wrong with your snake. But reading your posts like this shows how much you care for the little buddy. My Nibbler eats like a monster too so I can imagine myself also worrying in bits should she one day refuses for mysterious reasons. I just want to give you some comforting words, if they help at all, as I am not always so good with words:
We as pet owners love our animals so much that sometimes we either do too much for them. This can be both good and bad for the animal's wellbeing. As much veterinary medicine has taken steps to be better at diagnosing and treating disease that were once impossible to do so, we still know very little about our pets, may it be furry, scaley or fishey. I have many different types of pets and seen many vets for their ailments. I find that even the best vet may not have the answer. To say "I don't know what is wrong with your pet," is something you won't hear from them but in reality, there is much we don't know. How can we fix something we don't know?
Sometimes, like people, our pets can be born with genetic defects that don't kick in until much later in life. Some can be diagnosed, others are more difficult to find.
I am not suggesting anything ill towards your snake. You did the right thing by going to the vet. I am saying that sometimes things are out of our hands and you have to trust Corny to do what feels right to him. When he is ready to eat, he will. If he just wants to chill out for now, lets just wait and see what happens.
