Just wanted to say thank you for posting the information about lost cat behaviour on the web. It was instrumental in finding my cat Duke who suddenly vanished into thin air (or so it seemed) last Tuesday. I did the usual – stuffing lost cat flyers into 200 plus mailboxes in my area, talking to delivery men and mail men – no-one had seen any trace of him. I walked the streets umpteen times over the course of a couple of days hoping to get some inkling of what had happened to him. Thursday, someone posted a link to your information in a FB cat group I belong to. I started yard searching that very night. Friday after work I knuckled down to some more serious yard hunting, trying to work out in a circle from my own house. Numerous backyards later, I was about to call it a night and then decided to do a few more across the street. I had not been calling him as I didn’t want to risk being further from home than he was and confusing him. For some reason at that first house across the street, I called him. There was a faint meow from behind me. I called again, and he went into full on meow mode! There he was, up on the roof of the next house along, huddled by the chimney. What a relief! The weather had been horrible all week – snow flurries, icy, but he was in surprisingly good condition, although from the piles of cat poop he’d left up there, he’d been there the whole 72 hours. I think he may have chased a squirrel up a nearby tree, lept from there to the roof and didn’t have the nerve to try the leap back to the tree. Not sure who was more relieved that he was home – him or I! Thank you again!!
