Does anyone know of a 'premium' canned food that comes in larger cans than the 5.5oz? So like the 13-15oz cans? Right now mommy is using 3-4 of the 5.5oz cans per day, and if possible would like to use just 1 large can per day and store in the fridge, or is this not okay? It would be in the fridge for about 12 hours covered of course. Mom was just thinking it would be easier this way.
