This is truly heartbreaking. I’m so sorry for what you’re going through with your precious little tortoise and the fear of not knowing if your snakes are also infected. I will pray for the best outcome, and for your little guy who will be going to sleep for eternity tonight. I know this can’t be easy, but I believe you’re making the right decision for your tortoise, and for your snakes. Sending hugs and healing to you and your family.
