Human #586 missed his pet cat, Sebastian. Sebastian didn't have a tail. At one time he did, but he didn't anymore. Also, he wasn't technically Human #586's pet. He'd just show up at their house, and they would welcome them in for a couple days, until Sebastian was ready to be on his way again. He always came back after a couple weeks. But this time he didn't. Maybe he's out looking for his tail.
