Some are supposedly as big as cats!
Residents living between Belfast and Lisburn are being warned about an invasion of rats as big as cats.
Householders of a Co Antrim village say they have been invaded by giant rodents from the Mullaghglass dump, which is situated at Castlerobin on the outskirts of west Belfast.
The dump has provoked controversy since it opened in 2006, with residents complaining of infestations of flies and bad smells from the site.
Yikes. Sounds like they need someone to get over there with their popcorn popper.
