I realized that this cartoon (above) never made it into the book. Drat! This cartoon shows a pot setting right on top of a simple cat food can stove. This is the most common way to use a cat food style stove and the way I recommend.
This illustration (above) is in the book on page 100. This is another technique to use a cat food stove. This set-up with the 3 tent-stakes (as a stove stand) is rarely used, but sometimes it helps improve the burning depending on any number of circumstances. It works, but not as well as the system shown in the top illustration. This was an oversight, I wish the book would have been published with both these pictures, with this lower image being labeled as another option. I realize this might seem confusing to the readers of my book.
Here's a video of UL Super-Star Andrew Skurka making a Fancy Feast Cat Food Can Stove. He shows in in use with a small pot. If you are using a larger pot, just make a larger stove with a 3 3/8 inch diameter aluminium cat food can.
