Ratty

Had a walk to the lake in Ewell Court Park. I was watching a Moorhen eating some lettuce when out shot this creature. I'm not sure if it's a water rat or a water vole. 
I checked on Google and info suggested that amongst other things, a vole has furry paws and a furry tail half the length of its body. The rat has pink paws and a long pink tail. So it looks like this might be a vole. Having said that, the extra seems to be a different creature.
