Although I currently own neither a cat nor a dog, it has been my experience observing friends and the cats they love that cats are usually more harsh with computer keyboards than are dogs.
Napoleone certainly has her moments; but she is overall a pretty good kitty

Cats with different colored eyes aren't too unusual. And our calico cat Napoleone was split down the back like a Yin Yang sign. Several of my parents' cats have had similar splits on their faces, etc.
Never seen one that was a split between two solid colors, though.
