One question though, what do most vets charge for this service, or how much does the lab charge to do this? I think many would prefer to spend the money upgrading their chams enviornments rather than beating a dead horse so to speak.
price and what comes with it will vary considerably, particularly depending on how much a vet might even like doing necropsies. for instance, if someone called and wanted a necropsy done on their pet that was found dead at home, my standard gross necropsy fee started at $75 depending on weight (think cat vs. great dane). i would always explain to people that if we found something unusual in the tissues and that was to be sent off to the lab for histopathology, the lab fee could run another $120-200+ (but still optional). and then if we were the ones to do a cremation after, those prices would apply (but some would take home and bury). however, if it was an ER/ICU case, the owner had already spent a significant sum of money and they were willing, i would usually offer to do one at no charge because for me it's such an important learning tool. as bloodwork is so standard in these kinds of cases, after jiving years of elevated or decreased blood numbers with what was actually going on with an organ gave me a diagnostic and prognostic advantage, being able to visualize what was going on inside. and i doubt that i ever charged for a reptile in my entire career, just because i'm so interested and they were much fewer and farther in-between than a dog or cat.
in general i would say my costs were less as i had a rural practice, and not everyone does free necropsies. but some will, and many will use it as i did as a teaching tool for their staff members.
in terms of using the money to upgrade an environment instead, certainly one of the points that i was trying to make was that it may prove much more prudent to first make sure that your husbandry is indeed correct and did not cause the death to begin with, vs. assuming that it was a natural death. not all situations call for this type of situation, but if you have 3 chams die in a week's time, then many well wonder just what the heck is going on. and this would be the best way to get an answer.
