Voles everywhere!

We've had voles nesting in the shed, under the neighbour's step, recently they've been in a hole in the wall where the cat flap is (we don't have one now but more on cats in a minute) and either a vole or mouse in the hay that is covering the hedgehog house! Today, however, I spotted two on the garage roof feasting on some bird seed I had chucked up there! The side of the garage is covered in ivy. I assume they are nesting in there, rather than just using it to climb, as there was bird seed on the ground also - an easier option I would have thought, but then maybe they hope they are out of reach of the neighbour's cat who may as well have the word 'killer' tattooed across his forehead!
