Is there a semi-moist pouch food like this oldie but goodie WITHOUT "gravy" that can be left out all day for snacking purposes? I heard Tender Vittles was making a comeback and would be available at WalMart, but haven't seen it. I've finally gotten mine to eat wet food, but as I work all day, I can't offer it often enough and would like to supplement my old boy's calories. His teeth are going, so I don't do free-feeding with dry kibble anymore. Any suggestions???
