Also, expect this link list to change from time to time as I discover more tutorials, instructions, and research on how to feed your pets a healthy, zero waste diet at home.
My Plastic Free Life has a blog post about how she makes food for her cats here. There is plastic packaging from a supplement involved, but it makes much less waste than buying bagged and canned food would.
Recipes 4 Gourmet Dogs (I hate it when people write the number instead of the word it sounds like, but this is the name of the site, and journalistic integrity demands that I report it to you accurately, even if I got frustrated just typing it) has all kinds of great recipes that my dogs have loved, but I particularly enjoy them for their feeding chart for dogs by weight, found here. Feeding your pet at home is great, but not all of us have the time or resources to schedule sit-down time with our vet to quiz them on dietary requirements specific to our pet. This chart helps take a little guesswork out of the process.
