Unusual Disappearance

To try to rid the barn of our new pest, Joe bought a bucket of rat bait. 

He has been putting out 2-5 packets a day and it keeps disappearing.  He had been setting the bucket on that white chair.  After a couple of days, the bucket disappeared.  We couldn’t find it anywhere.  We were concerned someone stole it which would be a very strange occurrence.  I decided to look one more place,  through that narrow wooded door to the left of the plywood. 

I found the bucket, the lid was off, 

and several feet away.  Joe said the lid was difficult for a human to get off. 

The contents of the bucket were yet again, several feet away.

 This is one strong and aggressive varmit.
