If I were in your shoes, I would not hesitate to move my snake to work, no matter how long the drive is. While it's not ideal, most snakes that hurl a recent
meal only do so after actually being handled, especially when people fail to keep their head higher than their body. I also would NOT trust what they say about
chemicals that you can smell, & for as long as you can smell it, at the very least. Sorry to hear about your ordeal, not fun!
Some companies that spray these chemicals are used to thinking that "animals" means dogs & cats...& many don't care much for reptiles, so the thing to ask
is about safety for pet birds, as they are delicate too.
