Disclaimer before you read any further. You can indeed make your own cat or dog food. The good thing is that information is out there. You will need to read and research and get a well rounded scope of information before making your own foods. Dr. Karen Becker has great information out there. Catinfo.org is another great resource.
The "Two Crazy Cat Ladies" (who aren't too crazy) recently went on a journey to make their own cat food. You should check out the video below if you have a cat and see what they're up to. .
The great thing about videos like this is that it shows that it's POSSIBLE to make your own balanced meals for your cat or dog. Again, it takes a lot of time, effort, research, and dedication but it's 100% possible.
