^^What he said. Lol. But while everyone may be able to offer advice, a vet is always a good choice if you fear for your animal's life. At the very least a vet can give you a special dietary supplement that you essentially force feed the animal to make sure it is getting nourishment. I don't remember exactly what it was called, but when my skink had an RI and stopped eating, my vet gave me the diet for her and it worked wonders. Granted, prying their mouth open with an old credit card to shove the little dropper in there is not fun, but she healed much more quickly with that supplement helping to keep her energy up.
Thank you for your advice. Will the turtle be hurt if I pry her mouth open? (Need to know just in case)
