GREAT call LadyLiberty!!
although, (and this may be a technicallity), is Cheese whiz really a "cheese"?
That's cheddar... the pic is from Quiznos - they use real ingredients. Cheese whiz is not really a "cheese". It's a "cheese-food", whatever that means.
Cheese whiz is probably best to use as a dog treat... well maybe not, they probably shouldn't eat it either, though I've seen that british dog trainer use it.
