@@ipodsynca707 + Hi guy. My cat's feeding station is on an otherwise unused portion of countertop, theoretically so that the cat's & their food are safe from the dogs. But I have a counter jumping dog who jumps up there every chance she gets. So I've been searching the web for a cheap, diy, dog proof gravity feeding solution for 4 cats. Or a a dog proof system of some kind. I really like this idea/design. But you said any animal can eat from it. Any suggestions on what I could do, or how I could tweak the design to keep dogs out?
