I'm in Seattle, and we haven't had shortages of pet food since maybe April or May, but the Costcos around here have a limit of 2 per customer on the 60-packs of Friskies canned. Also, wet cat food always seemed to be on sale at Petsmart, but other than a small discount for buying by the case, it isn't anymore.

As part of my doomstash, I always keep a substantial backup supply of cat food on hand--it's always been at least three months, and right now I've got six months' worth.

I figure that if TSHTF, producing and distributing people food will be a higher priority than pet food, and I anticipate prolonged shortages. While I can eat all kinds of things, the cats depend upon me to provide what they need, and they can get sick from switching to new foods too quickly. So I've got them covered.
