but holy shit they are dumb sometimes.

I give them 'crunchy treats' that are the exact same kibble in their food dish. I just keep it in a separate little plastic container next to my computer. I make a big deal out of selecting and doling out each of the 4 crunchies they get [um, friskies maybe? a little yellowish one, a dark brown one, a light beigy one and a little reddish one. I think they are supposed to be fish, meat, chicken and beef.]
