I had to be out for a couple of hours. Before I left Cole demonstrated that he could pee and poop just fine in the litter box.

I just got home and he was sitting in the kitchen, not lying around like he was. He ate some of his food though not the whole bowl.

He seems to be on the mend. Maybe he nibbled something that disagreed with him?

Praying he is totally himself by morning.

Thank you for all your good thoughts!
