OMG, I just had the same episode with my Coco. I fed her and 1 hour later I went to get her and she wouldn't come out. Her gums were white and she was cold. She wobbled when she walked. I knew something was wrong. She had a blank stare to her also. I couldn't really get her to focus. I took temp and only got 97!!!!! I took her to an emergency vet. They think she could have a liver shut. Not sure since she is 1 1/2 now and never had any other signs. She had to spend the night at emergency vet and then I had to take her to her vet in the am. Her one liver enzyme was 461!!! Her vet suggested I take her to an internal specialist, so I drove her over and hour away. They did a sonogram of her liver and it was normal, now I am waiting for a bile acid test I think to confirm there is no liver shunt. I have to get her today at 4pm and find our what they found. She had to spend the night in this place too. I haven't had my baby since Monday. I have been a wreck and there have been lots of tears as you could imagine
I wonder if she could have been hyperglcomic (SP) She is a poor morning eater. I leave her food out because of that, but honestly she eats most of it at 4:30. I wonder if this could have happened if her sugar went from low to really high when she ate.
