For what reason did he give you the baytril? Did he do a sensitivity test on a bacteria sample, or did he just assume there was something wrong, and perscripbe baytril?
Too many vets simply give baytril to chameleons with health problems, as it's assumed to be a "safe" medication, and its use has very little risk associated with it.
I do NOT like to question the advice of a vet, but I'm going to do it anyway.
It is very nasty to chameleons. Unless you are pretty certain there's a systematic bacterial infection, I would not use it. My vet gave it to me for my male veield, who had severe burns, as a preventative against infection. He went downhill immediatly. I topped baytril, and he was fine within a day.
Every animal whom I've given baytril to foe a week or more has died. Since then, I have never lost an animal to infection.
Baytril can cause kidney damage, even to well hydrated and healthy chameleons.
Here's what you should do:
Contact your vet. Ask him if there was any immediate evidence of infection. Also, see if he is aware of the common side effects of baytril use on chameleons. Tell him that many people have observed some very nasty deaths as a result of its use. Esentially, let him know that it's got a reputation for doing bad things, and that it should not be used as a preventative measure, as the risks are pretty high. If he's seen evidence of infection, then that's fine. However, if there wasnt' any CLEAR evidence of infection, if the sickness was merely a calcium related problem, then DO NOT USE BAYTRIL.
Too many vets shotgunn reptiles. Plain and simple. Even experienced ones will treat every little problem they have with a shotgun blast, hitting everything they can think of, when what they need is a rifle bullet.
Weakness brought about by calcium problems, neocal glucon, UVB light, and a supplementation of Repcal with D3.
Burns, cuts, abrasions, bites, etc. Rinse with antiseptic wash, cover with antiseptic cream. That's it.
What my vets have done in these cases is shotgun the thing with antibiotics, just to prevent any infection. Unfortunatly, the chance of infection was small, the chance of death from kidney failure from antibiotic treatment was high.
