I don't know if this is the friend's case, but some of us live out in the boonies. There are other people with animals just as sick. I had to wait 3 days for an appointment recently. I thought I was going to lose my python. Snakes are a specialty. Not all vets will see snakes, at least where I am. There is only one Vet who sees snakes here, and sometimes, it takes a while to get in. In the mean time, you do what you can do to help it.
