They often poop right after eating. It usually looks like a brown pellet. Try feeding him in a separate bowl and see if you can collect a sample after he's eaten. You can scoop it up in a little fish net (or a turkey baster will do) and put it in a small plastic disposable bowl with a lid. Or a plastic baggy if you can be careful not to squash it.
