Nope! Just decided to be a disappearing asshole for 36 hours and come back like nothing happened.
edit: thanks to all for the different perspectives. he is fixed, has all of his shots, and has his own temperature contolled kitty condo (aka the laundry room) that we put him into every night. we have a pretty good network of neighbors and pieced together his activities via security cameras. he's a mouser for sure and that is his job until he decides to retire.
We lost ours for I wanna say 3 months. We had done everything, posters, nextdoor Facebook, craigslist, you name it. He was super old, and mostly an indoor cat at that point in his life. After a couple of months we just gave up on finding him. Then my wife gets a random text from this lady saying she thinks she found him. She goes on to say she found my wife's listing on lostmykitty.com which was a super random site someone told us to make a listing on, I was at work at the time n grabbed a box from the receiving area n cut a bunch of holes in it n headed to her house, but I was super doubtful that it was the same cat.
She was a solid mile or so away. I get there and sure enough, it was him. He smelled awful, and all his fur was matted to shit. My theory is my cat got scared and ran into or fell in a storm drain and got stuck because the lady's house was right next to the creek that those fed into. We had the vet check him out n she warned us that a lot of cats that go on similar journeys don't last long after because their kidneys go. He unfortunately was no exception. He made it another few months, but he had lost most of his weight, and he was in rough shape. We were super grateful that the lady found him and he got to spend his last days with us though.
