If any of those snakes were in the same room or even in the same building with the same ventilation system, they have been possibly exposed to whatever your one snake has. It's a little late to quarantine now if they have been anywhere near each other.

Like MiniJ said.... this probably wasn't the best thing to do for the sake of the sick and possibly other sick snakes. Pet ownership is a major responsibility specially when it comes down to being able to afford vet care when something should happen. Just because it was a "gift" doesn't make it OK to take it in when you know you are jobless. Also no pet is "free" by any means. They ALL cost us money.

I'm sorry but you have made some super poor decisions and should have read up on BP's and Boas back before you got one. If I were you I'd do my best to try to save the other ones you have, but you seem defiant on any help that have been given to you that cost a penny or more. Vet care is NOT free, pets are NOT free. People on this site are not vets but are willing to help others when problems do come up on finding a vet. All we can do is try to help you and point you in the right direction, YOU must then take it upon yourself to follow up and do the right thing. We can't just snap our fingers and tell so and so's snake to get better.
