Just another quick update. I finally got him to eat a few bites of his food plus a soft treat, drink a little water and then I carried him to the litter box and he made a small pee biscuit. Now he's in his favorite hiding spot near a heat vent sleeping. As long as he doesn't take a turn for the worse I think we can make it till morning to see the vet.

I really started to worry when he wouldn't eat earlier but now I think he feels a little better from the fluids.
