My cat ran outside when I came home a couple of hours ago. I let him out sometimes during the day, so he knows where he is and will come back, I just don't like him to be out at night. He's much smaller than all the feral cats in the area, and there are possums hanging around the neighborhood. I've been calling him but he's not coming. Stupid cat. I wanted to get to bed early, but I guess I'll just be waiting for him to come home instead. If he didn't make me love him so much this wouldn't be a problem.
ETA: thanks for all your kind words! My cat has come home, and he is fine. I woke up at 4am, having dreamed that he came back to me, so I went out to the porch to call him. He ran to me from the park across the street. Once inside he immediately went to his food bowl. When he finished his snack, he lay on my chest and purred at me for about 20 minutes before falling asleep. That's what I mean when I say he makes me love him. As a bonus, he was so worn out that he didn't wake me up for breakfast until about 9:00 am. I love my cat.
