KK

Koop's insane, yet adorable, cat. "KK" is actually an abbreviation of "Koop's Kitten", but was shortened to mimic the name of his other cat, CC. The "Koop" in "Koop's Kitten" is actually Koop's father (his name is Koop, too, as crazy as that sounds!). KK was gifted to Koop's father by their neighbors from their cats' litter when they realized Koop's dad really liked the little furball. Koop's dad has always had dogs his whole life, but knew Koop had CC already and with KK and CC likely biological sisters it was decided that KK belonged at Koop's house.
