He's usually all about the food. The three of them always stand around me looking up expectantly while I get their food ready. I don't think he's moved from his spot on top of the scratching post all day. We went to a movie and came home and he was still right there, same position and everything. John said the bowl right in front of his nose on the scratching post and he barely showed any interest. Just a couple nibbles then back to sleep.
That would be my guess, but I'm not certain. If he still isn't eating in the morning I'd call the vet.
I sometimes have trouble waking Jasmine up for meals, but all it means is that she's sleepy.
