Just a day since our local paper ran an article on how our city rats are getting as big as otters (due to all the junk food we drop for them) the BBC has run an article about how likely you are to see a weird array of creatures quite far from their natural habitats. The current reported sightings table is as follows:
5,931 big cats
332 wild boars
13 dangerous spiders
So you see it may not be big fat rats but in fact otters themselves wandering round our town centres feeding on Saturday nights scraps.
