The Auditory Similarities of Stonyfield Yogurt and Fancy Feast Appetizers: Un-Scientific Observations

From the reactions of my cats, I'm guessing that Stonyfield Yogurt and Fancy Feast cat Appetizers make nearly an identical sound while being opened. This is sad for my cats, since I eat a lot of yogurt.

Note Firefly's still-palpable disappointment moments later. (and least PETA come after me, rest assured that she got treats in exchange for posing for this photo.)
