By the way, all: Please, please don't feed your pets liver, unless it's from an organic source. The liver is the organ that filters - and accumulates - all the toxins that pass into the system. When you feed it to your pet, you're passing on all the toxins and poisons that were stored.
Kind of makes you wonder just how smart all those doctors and nutritionists were who kept telling our mothers to make us eat liver to make us strong and healthy!
