Cat
"Sam, look! Sam! Sam? Sammy! Sam! Look!"
Sam scrunched his already closed eyes, fearful to open them and see what surprise Gabriel had this time. "What is it?" he questioned carefully as a figure crawled over his body.
Gabriel leant himself over the top of Sam and kissed him on the nose. "Can we keep it?"
Sam's eyes remained closed. "Oh, God," Sam groaned. "What's it?"
"His name's Kurt. He likes short walks in the yard and kitty snacks," the angel grinned and dropped a light weight onto Sam's chest. The weight mewed loudly. Sam opened his eyes to find a dark grey kitten pawing at his collarbone. They stared for a moment, both sets of eyes widening at each other.
"Um, there's a cat on me," said Sam.
"I take recognition as an okay! C'mon, Kurt, let's go freak out your Uncle Dean!" Gabriel scooped the yawning kitten gently into his arms and treaded out of the bedroom. Sam took this as a sign that he could sleep again. His eyes drifted shut as he ignored the sound of Dean's scream from the bedroom next-door and fell asleep to the sound of Dean yelling, Gabriel laughing, Cas comforting and a kitten purring.
