I didn't even know about the snake/car incident until you just brought it up - and I wasn't going to say anything on here until you brought that up.

In your other post you said you were going to try to find this snake a home with someone who could care for it - I understand you are taking the animal to the vet but if you cannot continue to care for it please do find a new home for the snake with someone with the means to care for it, as that would be in the best interest of the animal.

You are only 13, a life is a heavy responsibility, not one you can end because you/your family cannot afford it. Do a lot of research, save up a lot of money for emergencies/vet bills, then think about getting more. Trust me - I have a rescue RTB that no one got treated, she has cost me almost $500 in vet bills over the past year and she is just now starting to get better. If a snake is left untreated for illness/injuries it will be that much harder to fix it later, so the sooner you figure out if you can handle what ever problem it has the better, because if you can't you can find someone sooner who will be able to.
