I remember a possibly apocryphal quote from a park ranger saying that there was a significant overlap between the smartest bears and the dumbest tourists.

I’m pretty sure I’ve seen this on some national park official instagram. The idea being they can’t build actually bear proof garbage containers because there will be people that can’t or won’t figure out how to use them. Experience dealing with raccoons confirms this… it’s difficult to contain dog food for a farm dog outside that doesn’t get broken into.

The only solution I've found is making the dog guard it. They climb to every place my cat can jump to.
