Question: I was in bed last night around 3am and I heard what sounded like cats fighting outside my house. That kind of high pitched yelp! Thing is there's no cats around here, I don't think I've ever seen a cat in my garden. This went on for about 5 minutes then stopped. Anyway, my question is what other animals sound like this? Could it be a fox or a badger or something?

Either that or I was hallucinating, as I was very freaked out.
