I definitely have a room to quarantine the snakes in, but for the next two weeks all of the snakes will be watched to see if any of them have diseases and need to be treated. So I'm sure they'll give me the word of what they want to stay and what I can foster.
I'll also check over the snakes while I'm there just in case I notice anything, so if I notice anything odd I would be sure to not take it with me. There was one specific baby Ball that broke my heart, it was so skinny it looked to be a stick. That one may be sick, but I could always take it back if I notice anything or while I'm there and ask for treatment since it is their snake I am fostering for. I do know the precedures to take while these animals would be in my care (such as cleaning their enclosures last, feeding last, sanitizing the tongs, cleaning my hands after handling or dealing with them, etc.).
