Thank you for the kind words.
Hor-Hey was the only beardie I had, the picture with the other one was a sibling from the breeder. Unfortunately, I lost the breeder's information, so I couldn't contact them with questions.
Also, he never ate in the tank with the sand. I have a 'feeder' tank, where he ate crickets, ect.
However...someone mentioned carrots. I had recently tried carrots with him, and chopped them up small. But maybe he ate too many and couldn't pass it. It happened so suddenly that I just don't know what happened. We had an appointment set up, but he didn't make it long enough.
Please keep negative comments to yourself. Although it would've been ideal to get him to the vet as soon as it happened, it wasn't an option at the time. You do not know my life, or the circumstances I deal with on a daily basis, so PLEASE don't point fingers or place blame. Prolapse is a painful way to go, I know. But trust me, I had called everyone, texted everyone, emailed everyone possible to try to get there. My boyfriend works while the vets are open, and by the time he got off work, Hor-Hey was gone.
As for the sand and impaction...it could be a possibility even while he never ate in the sand tank. I will never use sand again, and it is already out of the tank.
