I used to see them every so often on people in stores and such when I lived in NC, I moved to MA sometime around the covid lockdowns and havent seen one in person since, though Ive encountered people that like Trump vocally enough that Id not be that surprised to see one.
I keep my cat food bags inside an old pet carrier; its already designed for a cat to be unable to break through easily, and seeing as they associate it with the vet, they dont really want to go in there.
