To be honest, I was beside myself with grief and guilt, so my best guess is also that he was trying to prevent me from further blaming myself. I was at the vet with another exotic (kinkajou) in case I didn't mention it. I had just buried Sparkle, so no, no necropsy. He said that chameleons are fragile and that he doesn't keep them because of this. He quoted his last conference on the subjects of chams and said that D3 toxicity was very rare in actuality, but that adenovirus was prevalent, though not always showing symptoms or causing issues. My guess is the stress of the move (guilt) and then back again could have triggered it. The philodendron he thought was a possibility, but added that a lot of times they take a bite, realize it's bad, leave it alone, etc. I rarely saw him near it other than the first day, many months ago. Regardless, I am now far more educated on the subject and my other 2 (Senegal and Jackson's) appear to be fine, thankfully. Regardless, I will keep the D3 away from all of my reptiles and make an effort to give them some outdoor time. Problem is, it's very hot here (Ft. Laud) most of the time, so I guess partial shade, even in a screened cage is best?
I have captive bred fire bellied newts and my Caudata.org forum made me far more knowledgeable than any pet shop owner/employee, and I'd even guess, more than a few "exotic vets." The hobbyists really become specialists on their animals and I do trust them more than many "experts."
Thanks again for your support,
