Dying Grandis Day Gecko Please Help!
Today I found my grandis day gecko lying on the floor of my vivarium. His entire lower jaw was bent back under his neck. In other words, his entire lower jaw is now like a piece of rubber. Obviously, there is no way for him to eat at this point. He can still move his limbs at this point, but he cannot walk.
My first thought was that it could be metabolic bone disease. However, this seems a bit unlikely to me since I gut load my crickets with calcium and I use a UVB light bulb. I have also considered the fact that he may have broken his jaw by running into the side of the enclosure.
This entire situation looks pretty grim. The gecko can neither eat nor walk. He seems to be in pain. I am considering euthanasia. How can I peacefully end his life? Of course, before euthanasia, I will consider other reasonable treatment options if there are any.
Please, if you have any experience in these matters at all, contact me.
Thank you so much.
