This afternoon, I surprised the vole half-way up our Ikea shelves, tucking in enthusiastically to a small bar of chocolate it had found there that I had put safely out of reach of the dogs.
I now believe it to be not a sad Victim Vole, carried in by predators, but a bold Raiding Vole, nipping in through the french doors in the hope of finding loot.
Definitely a vole. Not a rat, not a mouse. Vole: little round face, short tail.
