Right, freedom, about the plastic. We have prepper friends who had a lot of food stored in plastic totes. The mice chewed into them and ruined quite a few. Now they put their plastic totes inside metal cabinets. But Tweva is right, mice can squeeze through incredibly small holes, compressing their pliable bone structure.
Metal garbage cans are excellent if you can find any that are strong. Not like they used to be… We used to keep our dog food in one with the lid tied down to keep raccoons out of it. With a good tight lid, excellent for mice.
