I used to make my cat's food, I bought an electric grinder to grind the bones, all the supplements. Buying the meat, chicken and organ meats and a bunch of containers to put the finished product in. I did this for about 8 months, I tracked my expenses and I could have purchased high quality canned cat food for less money. After 8 months I felt like I was a short order cook, I was cooking for myself and husband plus a cat. We also traveled in an RV several weeks during the 8 months, so I had to prepare and freeze cat food ahead of time.
