We did during the pet food scare. We're using Pedigree canned now with ONE. When I cooked, I would buy muscle meat (no ground meat), Hearts, and liver. I put a combo of meat in the crockpot with some sweet potato, green beans, and some oils that I got at the pet store. I would cook off of it then pulverize it all together in the processor. Then we measured out 3/4 cups in individual ziplocks and froze them. It would make about 22 days worth of meals. It was a lot of work but worth it at the time.
