Cats are good exterminators...Roaches are non existent in the house.
And I don’t think rodents will go anywhere they smell a cat has been.
They are also natural mousers.
Cats are also clean creatures.
There is a family up the street who has the exterminators in EVERY week. THEIR problem is filth. One needn't be a "seer" to guess which culture THEY are from. Their restaurants get closed with regularity over, er, "lack of sanitation." Their logic: "Why clean? The restaurant will just get dirty again the next day."
