Mikey doesn't want to eat anything yet. He threw up a lot this morning after he tried to eat. I gave him chicken noodle soup at the suggestion of Renee and he snifted it and just doesn't care. Now, I'm worried about him. I don't know what is normal cuz all of my animals are adopted as babies and usually are already fixed or done right away. He seems quite listless. I think the anesthetic hit him pretty hard. Any advice?
