Where we used to lived (next to a small river and fields in N.Yorkshire) one of our cats was on a one-moggy assault on the local wildlife. Used to get all sorts. Loads of mice and shrews, birds of varying discriptions, fish out of next door's pond, moor hens, some dirty great huge water rats, a bat, back half of a rabbit, a hampster (kept that quiet...), and even a kingfisher.
