well I buy mine from a British company... but I found this website for you if it's any good... We have squirrels here, but never had them chew through these bins...Hollydolly,
Do you know who manufactures these cans? I searched on Amazon (USA) but did not see anything similar. I have had squirrels chew holes in other plastic storage bins so might not work for me. They can be quite tenacious when food is involved.
