See, a cat is man's best friend.....
Unlike a dog, it buries it's poop.
It doesn't typically attack the mailman or howl.
It's great fun when paired with a laser pointer.
It reduces the bird population and thus the number of droppings on your car.
It rids your house of mice and rats that cause arc faults in attics.
In addition to that, your cat may be able sniff out electrical fires in the wall caused by MORONS attempting to wire a house as seen in the above post.
Nice cat!
