The fact that you're willing to take the snakes to the vet says a lot about your "suitability" for owning them. And if you're willing to learn and change as needed....you're good to go in my book.

So long as it doesn't contain any other medicines like pain-reliever...it should be ok to use. Don't slather it on...just dab a little bit. Keep the snakes on paper (newspaper or paper towels) and keep them warm and dry. No more soaking in anything until you have a vet's specific advice otherwise.
