We considered that option. It seemed wrong. We called my Dad. He agreed to stop in once a day, feed the cat, and be a human presence in the house for a few minutes before leaving Millhouse alone with his evil thoughts again.
Yesterday, as we drove home, the following exchange took place between me and my Dad, via texting.
Dad: "turd onfloor mil trying to ambush me"
Silence for awhile. Then we stopped for lunch at a fast food joint on the side of the highway, and while Spike was waiting in line for astoundingly tasteless burgers, I checked in with Dad again.
Me: "So is mill dead now?"
Dad: "Mil is good. we r friends he sniffs me but i am not 2 touch him EVER"
Me: "Lol sounds like a solid agreement"
Dad: "I have agreed 2 give him a nice funeral"
I haven't heard that there was a firm date given for that funeral, but we arrived home to a cat that was still in the land of the living, so I presume that the date is TBA.
Happy New Year from Spike, me and the ever-malevolent Mill.
