I keep my birdseed outside, and I now use a galvanized trash can. The squirrels chewed through the green rubbermaid container I had been using. The can is on the smaller side and has a handle that can swing up vertically and it locks the lid in place so the squirrels (or other critters) can pop the lid off. I've never had a problem, and it's been outside for at least 5 years. Oh, I bought it at Agway, but they've since gone out of business (at least in NJ).
