Last time I had a cat that wouldn't eat they were in kidney failure. There's probably other reasons that a cat would stop eating that aren't that serious, but if you can I'd say take a trip to the vet just in case.

He'll eat, but only when I give him a new scoop of food or a treat.

I think he's just being picky.

Yeah, that sounds picky to me.

I guess just try feeding him meals on a schedule rather than leaving a whole day's worth out and see if he likes that better. My cat is the opposite, she'll devour everything in the bowl and throw it all up if I put it all out at once.
