Your roommate brings home a cat.

You are doing work at home since you're sick with a cold. You sent your roommate out a while ago to go get you some medicine since you didn't have any in the house.

You hear the door unlock, and your roommate comes in the house, you hear the door lock. You walk over to the living room, and he is sitting on the couch with a cat you haven't seen before.

Where the actual fuck did he get a cat?
