I realized I hadn't seen my (indoor only) cat for a few hours, so I started looking in the usual places around the apartment. There was no sign of him. I started looking in some weirder places. He wasn't there, either. I did another sweep of the normal spots like my closet and under the bed. No cat. That's when I started getting nervous and got ready to go look for him outside. Before I went out of the door, I looked in one last spot in the kitchen, and that jerk was in one of the cabinets under the sink. I never look in there for anything, so he could have spent a long time in there. Serves him right.
