I have a pot of agapanthus buried into the back garden. Twice now I've gone out to find the agapanthus upended and an empty tin of dog food buried there.
The first time I thought foxes, the second time I'm not so sure. Last week I took the tin out and put it next to my chicken run and reported the agapanthus.
I've just been out the front to find the tin has been replanted in my new strawberry bed and 2 strawberry plants have been upended. Only when I went to replant them did I notice the entirely buried dog food tin.
Yes, it's the tin from the back garden (70 feet away)
There is no way an animal has done this right? 
A large house that backs onto us may be some sort of half way house as I've been yelled at by young men a few times when in the garden.
I'd really like another explanation before I talk to the rozzers and say 'there's a dog food tin wandering round my garden appearing in unlikely places'
