well this time around our reptile show is a 2 day event so if I find something I can make sure i know what it is and go back the next day. Given the fact that what I did buy from the guy wasn't healthy and died anyways it might not have made a difference, as all his animals may have had issues. Also, being as how the animal has been brought in from somewhere across the country in a plastic tub and left sit on a table for 4-6 hrs (the show is 6 hrs long..or at least it has been) plus the trip back to it's home if it doesn't sell, the animal is already "at risk" and within a day or so I can probably nail down the basics for most things, like temp, and even if I don't get the cage size right right away, that wont kill the animal. I actually scolded one guy for having several Uromastyx on the table all afternoon cold to the touch. No lights at all. There's a petland a mile or 2 away I can get materials in a snap if I lack something, like a heat lamp that wasn't big enough or wrong size food items.
