Did not work. It says on the package that they don't work on cans opened with safety can openers. But our cat food utilizes pull-tops, and though I suppose that might make a difference, and that these could work with cans opened by a can opener, I don't see how. The "seal" created (by pushing this thing down into a concave shape) began slowly letting air back in right away.
