I don't get what the big deal is. This whole germ argument, it's preposterous. So you don't eat them raw. Fine. I cook mine, well done in fact (it's not beef, after all).
And here's the thing--they're tasty, nutritious, and no one's out anything. You eat a rat, one more baby will grow to adulthood. No big deal. It's not like eating spotted owls, or anything.
Rats aren't that hard to catch either, not really. They're plentiful, they're great with mango and cranberry chutneys, and you can use the remnants to make some really nice throw rugs.
I just don't understand why so many people make a big deal out of it.
Come over and have nachos some time.
