After my cat had surgery she had to wear an e-collar or "cone of shame" for ten days to prevent her from irritating her stitches. But the collar made it difficult to eat from her usual dish. She simply could not get her mouth to the food before the e-collar pushed the dish away.
So I made this simple stand from scrap wood, rubber mesh, and hot glue. It holds a small saucer at a 15 degree angle a few inches above the floor so the e-collar can pass under it and allow my cat to eat. Adjust the size to fit your pet.
