LOL good luck finding any company willing to cover medical on a 26 year old horse.
That brings up another point when taking a snake to the vet when it has an RI - how many vets won't bother with a culture because it can double the total bill? While many folks here probably have a few hundred to put into a sick morph even if it meant living on Ramen for a while, the vet also sees cheap snakes with advanced RI's whose owners tried at-home treatments while the animal got progressively worse. So, rather than sock the owner with a $350-400 bill - and pretty much ensure the next time the snake gets sick the owner will most likely just let it die - they charge $100-175 for the visit + antibiotics, and save the expensive cultures and treatments for the very few cases where pushing Baytril + Fortaz isn't enough.
