He has not eaten for me, I have had him five days. He is fairly large so clearly he has eaten but his owner said not in the past few months.
I am not considering euthanizing him right now, I will of course allow him time to settle but it is much, much more severe than that. The top third of his body is upside down, head constantly spinning or literally moving upside down but completely unable to move normally or even stay still upright.
He is also not lifting himself off of the ground, he is moving only on the ground upside down
