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 snuck our cat into our apartment skirting the lease. About 4 years in, they noticed our cat. We were given the ultimatum, pay $500 by the end of the week, or get rid of him by the end of the week. I was absolutely devistated, but we had no choice but to rehome him. We found a nice family across town to take him in. They would send us updates for about a week until he ran away.
About 6 or 7 months later, I'm watching TV with my wife at midnight, and I hear frantic meowing at the door. It was him!
The management company was in such disbelief, they waived the fee for us and he lived to be 12 years old. He passed away in my arms about 2 years ago. I'll never forget him.
