Dwarf Gators?
This is one of those unknown knowns that occur when dealing with living things in person - Once you leave the show, you're pretty much on your own........
Look at it from a Vendors perspective - You bring a healthy animal to a show, sell it, and it's dead a day later - There are about a million and one ways to kill an animal in that time frame, that have nothing to do with the vendor.......
It all comes down to the individuals terms of service, and usually when you deal in person, there are none..........I've been on both sides, and whenever I end up with someting dead, I suck it up and move on. I've had people cook animals in there Cars, then try to bring them back telling me it was my fault, along with a myriad of other excuses as to why they killed whatever they bought an hour earlier.......
Sometimes things just die......If it looked healthy at the show, then who knows? If it didn't look healthy, then you made a gamble and lost........Any herper that's done this for more than a few years has been in that position........
At the end of the day, these are living animals we deal with, and nothing is ever guaranteed in the game of life.......
