Our feed store delivers in 55 gallon barrels. They unload the barrels into the shed , and I leave them there.
It’s great not having all the trash build up… the feed sacks I mean.
I used to have bajillions of mice, which would have been a problem because the lids on the barrels don’t necessarily fit tight, unless I put the clamp on, which I don’t want to bother with!
The barrels are rotating stock. They arrive full and depart empty so there’s no point trying to adapt them for a tight fit.
I had some half grown cats show up a couple years ago. I fed them and tamed them and they stayed and multiplied. They’re all neutered now (5 of them!). They keep the mice out of the house and all the outbuildings. YAY.
I used to keep the cat food in a high quality Brute trash can with lid that latches down, but the cats took the lid off at their convenience.
The cat food is now stored in the house. For now, things are working.
