I use the Gamma2 food storage vittles vault containers and haven't had any issues thus far. They're completely airtight and while I mainly keep in my garage, a few years back when we went on a 3 week trip, I left it out for a neighbor to access for refilling feeders and no animal seemed to even attempt a break-in. Concurrently have never had issues with rodents in the garage because it's well sealed and thus doesn't release any odors.
