Yeah right! We never had any problems with rats or mice until we got a cat. He was a kitten from a farm, and turned out to be excellent at catching rodents. Problem is he usually brings them in alive (or occasionally half alive) and throws them squeaking on the carpet from where they disappear under the furniture etc etc. We actually had one living behind the washing machine and one in the chimney behind the gas fire for 6 months. We dared not put poison down because of the cats, and eventually caught both rats with humane traps. (They were coming out to eat dried cat food at night). Now we just keep kid's fishing nets around the house ready to catch any live baby rats/mice as soon as the cats release them. (We now have 5 cats, and 3 of them hunt).
