My gf and I have 3 cats. We get the big cans of hippie-friendly cat food, and dump the food into a plastic container that we keep in the fridge. Sometimes when we open a fresh can, we let the cats lick the can.

Sophia (a.k.a. Sofa Loaf, a.k.a. Loaf, a.k.a. Loafenstein, a.k.a. Loafelberg, a.k.a. Tomato Cat, a.k.a. Egg Cat, a.k.a. Gurrrl) here got her face stuck in the can for a bit. But she accomplished maximum cat food can lickification.
