Squirrels are rodents who live in a slightly better neighborhood than their cousins, the rats. Push comes to shove, they'll eat anything. The only reason they don't scavenge around here is because of all the bird seed they steal from the feeders in every back yard. We are talking some very obese squirrels, let me tell you.

I was talking talking about grass-eating, cud-chewing animals with hooves and no canine teeth. Then it occurred to me, mad cow disease was spread by feeding cattle a supplement that included the ground-up remains of dead, and unknown to the farmers, infected, cows. So grazing animals can eat meat or "meat by-products" (a term that has always quietly terrified me anyway).
