I know online people that BUY freezer burned meat (from hunters) just for their furkids.
I've known people who did, too. At the time, my focus was on dogs only. I think there are lots of things you can give a dog that might not be okay for a cat. I knew one woman whose advice for dogs was, throw out meat only when it smells so bad that the neighbors complain.
I'm pretty sure she was joking, but she
was the same one who picked up road kill to take home. Her dogs would eat, bury the leftovers in the backyard, then dig it up the next day and finish it. I'm not quite ready to get that "natural."
I'm sure this stuff will be fine, just wanted a second opinion. Chicken feet for the dogs, gizzards for the cats.
