Welp, I was able to get a vet's appointment around noon today, so Rick and I took a long lunch and took Carmen in.

My vet said she's never seen a reptile react to sub-cutaenous Baytril injections in "the 20 years she's practiced with reptiles". She prescribed a topical anti-botic, Silvadene 1% (silver sulfadiazine), applied as a thin layer once a day to the 6 "scar" spots (we counted) and set up a check up for next week, all gratus. She also recommended that we remove all cage items (save her water bowl) and replace the aspen with a good fluffy layer of ripped up paper towels (as substrate and to hide in), so she doesn't get any possible infection from the aspen and she'll still have something to bury and hide in.

Anyone heard of Silvadene/silver sulfadiazine?

Oh, vet said that silvadene was developed for human burn victims, but it is a negative (something...what was the word? related to the type of germ, either positive or negative) topical anti-botic and regularly prescribed for reptiles with burns. Sound familiar to anyone?

Rick and I have pretty much decided to find another vet for the snakes; while I know you can't take everything you read on the internet as solid truth, the fact that I found so many references to sub-cutaneous Baytril causing necrotic scars really makes me believe there's gotta be some truth there. I'm bummed - I really like/liked this vet. *sigh*
