I'd love to feed some of that stuff. I'm not a skickler for "must have 20 different kinds of meat in my dog's diet", but muskrat, goose, and fish - I'd love to go a bit different! But you're right on the price, we limit out at about $.75 at the ultra-high-end. Usually $.49. Some of the meat is more than $3 a pound, and that would get a bit steep for three dogs x one pound per dog!
But I might try out the antlers, and the bison bones are $1 a pound, that's not bad!
Inside me is a thin woman trying to get out. I usually shut the bitch up with a martini.
