I jsut checked back in and I'm so sorry to hear tha Chance is still not well. It is a wonderful sign that he is eating and drinking. I remember when Peanut Butter did the same thing. He didn't move from the same spot for two days. He would get a drink every now and then but then right back to his chair. I found myself doing like you...checking him for breathing, and constantly watching him. When I got him to the vet it turned out he had a really bad sore throat! Medicine took care of him quickly but it was scary until then. They are so pitiful when they are sick.
We are still praying for Chance and hope he feels better soon.
