This is by no means an exhaustive list, but it is a starting place. Remember, it doesn’t have to be expensive or complicated. Just start somewhere making small changes where you can.
You don’t have to buy buckets! We got ours for free, but here is a link to some if you want to purchase or want to buy bigger containers. The only thing that matters is that they are air tight and food safe.
Again, you don’t have to buy powdered food or even from a “bulk store”, but these are some of my favorites if you choose to.
Azure Standard is more of a bulk buying supplier and has lots of options if you have food allergies or need a specialized diet.
