Spooky appears to have recovered, except that his amnesia returned -- he forgot where his catboxes are again. Luckily Terry caught him in time to adjust his location. We're hoping that was a temporary aberration.
We figure he ate something that disagreed with him. I did give him leftover Hawaiian BBQ ribs on Monday, and was surprised when he ate the pineapple bits. Perhaps that caused the problem. Or perhaps it was something in the BBQ sauce, which was store-bought. Pork is Spooky's favorite meat, and everything tasted of pork, so he ate it all.
