If you want to see a "real" mouse problem, google "Australian mouse plague". Where my daughter lives (west of Brisbane) if you drive at night there's a moving carpet on the roads. Just billions of them. Actually, that was a year ago, not as bad now.

BTW, I now remember why I don't like cats. My mother had a cat and whilst watching telly with one of my early girlfriends it was cuddled on my mothers lap, it got up, walked over everyone and threw up in my lap. It then proceeded back to my Mum's lap and settled back down. How could I not be traumatised by that?
