Apocalypse Cow by Michael Logan

If you like Mars Attacks you'll love this. A hilarious and completely sick thriller in which a deadly virus is unleashed on Britain, via a lab in Milgavie. An infected cow turns up at a nearby slaughterhouse and chaos ensues. The virus gives the cows a taste for blood, for raping anything they catch and enhanced strength and resiliance, they are harder to kill than a normal animal. And the virus can be passed on to any land based animal except humans. Cue killer squirrels, bunnies and sheep, out for revenge on the people who have exploited and hunted them for thousands of years. 

The only hope for mankind are a rash infested horny teenager, his vegan ecowarrior parents and their new money neighbours, an escapee worker from the abbatoir and an inept journalist. As Europe closes its borders the small band travel from London to the Channel Tunnel in an attempt to escape the virus before it mutates and infects humans.

Living in Scotland did help, I understand the ironies of a peace loving hippie living in Cumbernauld and of yobs getting their comeuppance in Easterhouses when their muscle dogs get their revenge. This is one of those books that is so unfunny it's hilarious, the satire is biting and spot on, the ironies pile on top of each other.
