Male cat.fixed.4 to 5 years old. Formal feral. He's been an inside cat for a year no problem. We could have the front door open, and he wouldn't even look or think of going outside. All of a sudden at midnight when my mom had the door open to talk neighbor,and he bloted outside and into the forest. It took an hour and half for him to come home. I had to dive for him and grab him by the tail to get him inside. Which i feel awful doing, but it was the only to grab him. Hes not hurt and still his lovey self. Now that he's inside though, he won't stop walking around the house meowing and checking everything out. He's been doing it all night and morning. He won't go to sleep and won't leave the front door alone. What changed? Why does he want outside so badly?
