I think that's absolutely disgusting to keep it alive, moreso to advertise it on the net, and criminal IMO to put a price on it.
I agree they shouldnt advertise it and try to sell it. I dont know if I agree with killing it, I feel it should be given the best care it can like any other animal. 2 headed animals have survived before, I have seen several 2 headed adult snakes that are surving.
You're probably right, i know i sure would not have the heart to put it out of its misery.. although sometimes you have to consider the animal's wellbeing before your own comfort. The owner claims that both heads eat (not that this is at all an issue as the beardie clearly only has one stomach) but whether its way of life is hindered i'm not sure.
I would be very interested to see how it formed, whether it is a conjoined twin or a genetic mutation that caused it to intentionally grow an extra head in such a manner.
I still maintain it is disgusting to advertise and sell.
