This is an older project that came out of necessity because I was tired of having cat food bowls everywhere. Also at the time we had a large dog and we had to keep the dog out of the cat food. I sized the lid over the trough by holding a piece of plywood over the largest cat while it ate. The rest was using scraps of pine and plywood with some tongue and groove to keep it together. The pieces that hold the bowls keep them off the floor so it’s easy to sweep up escaped kibbles. The edges are rounded over to make it more esthetic for the kitties. A little white paint and the project was complete. I later had to add a larger lid and support because we acquired a smaller dog and we had to keep him out. You will notice the picture with the cats has the smaller lid.
