Our Cthulhu cat (a black and white) was much like Murphy. He ruled the household firmly, including running out various kitty brothers, until we finally found one who was a happy and mellow companion.

We lost him to kidney disease, way too young (at age seven).

Hunter Cat, his final companion, lived to be thirteen and died from cancer. He had firm opinions about how his boy should be raised, including bedtimes which included the required feline cuddling, and Hunter's presence at noisy young boy video game parties (required).
