Was the kibble (I assume) in a bag or just loose in the metal barrel?I opened the container with the dog food in it and it was disgusting. the food had started to crumble up and it smelled very stale and yucky. good news though, no mice droppings! no mice had been there in over 40 years (one sign on the wall actually said 1981)!!! gross but awesome! I will definitely be using the containers once I give them a good disinfecting! hope it works!
Might be a date on the bag...just out of curiosity.
Good no sign of mice, that could have smelled worse.
