The myth about cats being good rodent control has been disproved on every island where cats were imported to take care of the imported rodents. Hundreds of years later and there’s nothing but a thriving population of cats and rodents – all the native wildlife on those islands now either extinct or on the brink of extinction – even those native species which are better rodent predators than cats (such as many reptiles and shrews which destroy rodents right in their nests), the cats having destroyed them directly or indirectly.

The rodents reproduce in burrows and holes out of the reach of cats, where they are happy to reproduce forever to entertain cats the rest of their lives, and make your own lives miserable, on into infinity. On top of that, when cats infect rodents with cat’s Toxoplasma gondii parasite, this hijacks the minds of rodents to make the rodents attracted to where cats urinate. http://scitizen.com/neuroscience/parasite-hijacks-the-mind-of-its-host_a-23-509.html
