Kitties, I swear, he was back again this morning and though I shouted un-ladycat things to him through the window; still he stayed gazing. Mom came with the Nutri-Vet calming spray, sprayed the air with it and left the room again while I continued to give instructions to the Maine Coon.
Mom mistakenly thought that was it for the day as I ceased imprecations hurled against the glass--- but sadly no. He was perched high up within spittin' distance right on top of the heat and air unit outside. Mom went back for more calming spray. After administering it to the air again, she pulled on a shirt and went outside to ask after his family and how were the wife and kids.
He departed in a dignified and slow manner but he did leave. I am still jumpy and upset.
Mom loves her little figurine. Bet you can't tell why. MOL.
