I’ve only had one cat, a mutant 20 lb orange tabby from Hell who appeared in my driveway one rainy morning as a sweet little kitten. Very smart and mostly amiable cat (taught him to sit, shake, could be summoned with a whistle...taught himself to use the toilet all on his lonesome) but would lose his mind once in a while. Almost 15 years later I still have a pretty wicked scar on my right thigh from that SOB.
R.I.P, Buster.
May you meet the SOB at the Rainbow Bridge.
