Opossum in the shed eating pet food

Example No. 1:

 

There is an opossum in the shed eating the dog/cat food.

 Wrong Answer:

Trap the opossum and relocate it. This will provide a short-term solution but not solve the problem. In a few days, another hungry animal will be back in the shed.

  Right Answer:

Seal the pet food in a container with a tight-fitting lid, seal openings to the shed and relocate the opossum. This removes the problem (pet food in an open and accessible container) and the symptom (a hungry opossum). Problem solved.
