Another thing you should know is that Baytril causes necrosis at the injection site. A good exotics vet does not just hand the stuff out like candy without a culture and tell you to dose up all your snakes. It should be properly diluted and depending on the amount, each injection should be administered in 2 or 3 places so that the entire amount in the syringe is not being concentrated into one area.
If not done properly, you can end up with sores and scabby areas at the injection sites that turn dark and may or may not ever completely fade away.
Every snake reacts differently to it as well. Some may not have a problem, while others will.
This is why I always tell people to try to find an exotics vet. My vet only does birds and reptiles. I know not everyone has this option and if you don't, it's worth a few phone calls just to get some phone info from one. That way you may be able to help educate your own vet. Or at least give them something to go on so they may do some more research on their end.
Just make sure you have a diagnosis before you start medication all your animals in such a way. If you feel you don't need a culture for each one, or can't afford it, make sure you learn everything you can about Baytril first.
