People often joke that cats have a sixth sense for finding the trash, and one way to outsmart them is to create a barrier around the garbage can using a sturdy hinge made from a 3.5mm welding rod. Next, fashion a pull stick from a 2.5mm welding rod. Three beads will serve as the perfect counterbalance, keeping the device steady while you use it to deter your feline friend's trash-diving antics. For the trigger mechanism, salvage a spring from an old bic lighter – its tension is just right for snapping the device shut when the cat tries to knock over the garbage can.
