Bread. My cats are obsessed with bread. If any kind of bread product is left out, I can gurantee you will find it ripped apart on the floor within minutes whether it be bagels, whole bread loafs, french bread or crackers. Angel and Abby will go through great lengths to get at bread products; they will rip through bags, hop on top of fridges, and open cupboards. As of right now, I have the bread on the very top shelf of my highest cupboard, right next to the catnip, and if they haven't gotten to that yet, I think the bread is safe.
