I thought the same thing, the lion did that too, so I was thinking ok it just cant see, but we can work with that. I would hold a piece right in front of his nose & he acted like he wanted it, just wouldnt eat it. Plus I could see his eyes following me, just grasping at straws. I think he really wanted it, but the blockage must have made him feel full so he refrained. I hope you have better luck, it's got to be the hardest thing to watch one starve to death & there is absolutely nothing you can do.
