Roadkill. Dude's hobby (and probably his livelihood) was turning worthless roadkill carcasses into art. He also had 9 lizards that he was keeping properly, and 6 in conditions that didn't meet the "required animal welfare standards".

Doesn't say what "standards" he was deficient in with regard to those six out of 15, but based on the rest of this article, I'm inclined to give him the benefit of the doubt that the particular standards he broke for those lizards are some technical infringement rather than actual abuse. Nobody takes care of 2/3 of their animals properly and acts neglectfully toward the remainder.

From this article, it seems the proper "punishment" would have been to assist him in filling out the paperwork for his taxidermy license. He obviously knows the job.
