Birdsgo Dog Feeder

We have an Indian Minor problem locally, they would spread dog food everywhere, crap on the patio, crap on the outdoor furniture and also on the clean washing on the clothesline. I designed a simple
feeder which no bird can access. It also protects dry food from ants, snails or slugs and even cockroaches. I have been using it for at least ten years. I had a provisional patent on it but have never pursued selling or manufacturing.
