Two year old, 20 lb., neutered, long-hair, gray tuxedo, 4-cylinder Mitsubishi with squeaky fan belt purr, picked up by daughter as a stray hanging around work 'bout a year ago (ditched by college kid at end of kittenhood?), absolutely refuses to consider allowing the four "senior partners" to continue existence: 16 yr. old, neutered, gray DSH, down to a rather gaunt 7 lb. from a very chubby 15, working on mo. 20 of "one month, two at most" (feline facial cancer), still eats like a bottomless pit full of hollow-legged wolves; his best buddy, 14, 15 lb., long-hair, neutered, toasted marshmallow ragdoll; and "the licorice brothers," neutered, 12, 15 and 20 lb. medium hair. The aggressive behavior? Nothing so civilized as the "Kzin 'scream and leap,' " --- it's more "leap and attempt to kill." Actually a little terrifying in a way --- no flattened ears, raised back hair, spitting or cussing --- just go for the "leopard vs. Lucy" occipital bite and basal skull or cervical fracture. PestMart (sic) doesn't take drop-offs; we're leery of turning him into the local shelter with his attitude toward other small animals; and, we aren't about to try the "gato a gato" approach to socializing --- scrappy 7 lb. cancer case vs. 20 lb. street fighter ain't gonna work, and the other three are pacifists --- territorial about the yard, and ornery, but still pacifists. Anyone got ideas on socializing a people loving, cuddly, fastidious, bright, cooperative ("Stay inside the fence? No problem." --- excepting --- "Leave the other cats alone? My long-hair, gray a**! Lemme at 'em!") cat? After a thoroughly punctured palm and 20 lbs. of scratched up licorice face this weekend, we're at wits' end.
