Update: Merlin has been found and returned home safely. Apprently had just wanted to put in a maintainence request><
So, i came home from work yesterday and the door to the porch was open and Merlin, my cat was outside. So i sat out with him for a bit, let him explore the small amount of outside he could get to and brought him in. As i brought him in i pushed the door almost closed but not quite.
I stepped over to help Renee with dinner and the fuzzy bastard must have slipped back outside because he wasn't here this morning. Best guess is he's been outside at least 12 hours. I looked for him for a bit before coming to work today, mostly around the busy streets nearby, and i can say with an amount of confidence he's still alive. But twelve or more hours is a long time to be outside for an indoor cat.
Wherever you are now, you purr box, come home k?
