Review on Gamma2 Seal Lid - Pet Food Storage Container Lids - Compatible with 3.5, 5, 6, and 7 Gallon Buckets, White, 4122E by Angela Anderson

A little tricky to put the ring on, but worth it. I've had a long-standing problem with raccoons and possums getting into cat food and bird seed that I wanted to keep away from metal trash cans, and they soon frustrated my efforts. Screw caps are great for human hands, but not living creatures.
