Dean bolted upright in bed. He'd just been having the most peaceful sleep he'd had in weeks and suddenly he was awakened by the feel of something fluffy brushing against his nose. It was still dark in the motel room, and Sam was fast asleep in the bed across the room. Dean tried to get his eyes to focus as he scanned the room for any signs of movement. Then the covers made a noise. Shit.There was something on his bed!

His first thought was that it was a damn rat. He quickly grabbed the knife hidden under his pillow and held it tightly in one hand. Throwing off the covers, he stepped out of bed slowly, squinting his eyes in a vain attempt to see in the dark. Suddenly, there was a noise. A noise that sounded suspiciously like a kitten's 'meow'. Dean looked around frantically. He'd never heard a rat make a sound like that before.

Eventually, he got fed-up hearing rustling noises and feeling as though some creature was watching his every move. So, he trudged across the dark room and flicked on the light switch causing Sam to groan and his eyes to open slowly.

"Dean," he grumbled, turning to look at the digital clock which sat on the nightstand. "What the hell are you doing? It's three a.m."

Dean let out a frustrated sigh. "Dude, there was something in my bed. I can't see in the freakin' dark."

Sam rubbed the sleep out of his eyes and stifled a yawn before sitting up to face his brother. "Having something in your bed isn't that unusual, Dean," he mumbled, chuckling softly.

"Shut up and help me find this thing. I swear, it sounded like a-"

"Kitten?" Sam asked, eyes fixed on a spot across the room.

Dean's eyebrows furrowed and he followed Sam's gaze to see a tiny, grey ball of fur. He took a few steps towards it to get a better view. The little kitten looked up at him with wide, blue eyes. Its tiny button nose was the pinkest pink and its long, bushy tail swung back and forth behind it. Dean felt his heart flutter when the kitten let out a soft mewl. But, no. Dean was a manly man. He was not going to be won over by some stray cat that just happened to find its way into their motel room.

"Must be a stray," he mumbled, looking for any sign of a collar around that tiny little neck. "We need to get rid of it."

"What harm could a kitten do, Dean?" Sam stepped out of bed to stand beside Dean looking down at it. He crouched down to eye-level of the tiny ball of fluff and reached forwards to pet behind its ear. The kitten made a warning hiss and Sam pulled his hand away quickly. Dean couldn't help but let out a chuckle.

"Man, I don't know," Dean said, sarcasm dripping out of every word.

Sam rolled his eyes and stood up, still peering down at the unwanted visitor. "I dunno. He sorta reminds me of someone."

Dean furrowed his eyebrows and tilted his head, his gaze still locked on the kitten, trying to figure out what Sam meant. "How can a cat remind you of some-" Then the kitten tilted its little head and Dean's eyes widened. If that little furry creature had a tie and a trenchcoat on then it would be the spitting image of... "Cas," Dean whispered breathlessly. He then turned to stare at Sam, bewildered.

"We haven't seen him in a few days. Maybe..."

"No," Dean began, shaking his head. "That's not possible. It's just some jacked-up coincidence."

"Meowr." The kitten was now just inches away from Dean's feet, staring up at him with those impossibly blue eyes. Dean fought the urge to pick the tiny ball of fur up and cuddle with it.

Sam crouched down again, only this time he didn't make any move to touch the kitten. "Cas, is that you?" he asked, feeling kind of stupid, talking to a cat.

The kitten shot him a look that said, 'obviously, moose-boy' and then proceeded to walk across the room and pounce up onto the table where Sam had been researching earlier. He'd left a number of books on the table and the kitten looked as if it was searching for a particular one. It then flipped open a book, with some difficulty as its paws were so tiny. Dean walked over to look down at what the cat was now pawing at.

The kitten had flipped the book open to a page about biblical angels and was now scratching at a picture of none other than the archangel Gabriel. Sam looked at Dean with a stunned look on his face.

"You think he turned Castiel into a cat?" he asked.

Dean shrugged, watching the kitten hiss at the picture of Gabriel. "He's done stranger things. Let's summon the son-of-a-bitch and find out."

After gathering the things they needed in order to summon Gabriel, Dean and Sam waited impatiently for the archangel to arrive. Luckily, they still had some holy oil left just in case he decided to try and make a swift escape.

"You called, boys?" Gabriel asked as he appeared with a flutter of wings.

Sam turned around and glared at him. "Did you turn Cas into a kitten?" he asked. Okay, that line definitely made it into the 'Top Ten Weirdest Things Sam Winchester's Ever Said' list.

Gabriel pursed his lips together, obviously trying to hold back a fit of laughter.

"Why the hell did you do it, Gabriel?" Dean asked with his arms crossed and his best bitchface on. Not as good as Sam's bitchface #52 but very close to it.

Gabriel looked deep in thought for a few seconds before letting out an amused giggle and shrugging his shoulders. "Just felt like it."

Dean sighed exasperatedly and rolled his eyes. "Whatever. Can you just change him back now?"

"Hmm... Nope," Gabriel said with a large grin on his face.

Dean looked to Sam with a look that said, 'help me out here, man.' Sam then cleared his throat and straightened himself up. "Gabriel, listen. This can be sorted out the easy way or the hard way," he said, grabbing Dean's lighter and flicking it a few times.

Gabriel's face dropped and his gaze fell to the ring of holy oil around him. He groaned exasperatedly. "The Holy oil trick? Again? You guys really oughta up your game a little. The surprise factor really ain't workin' in your favour anymore." He then looked at the little kitten and rolled his eyes. "I can't break the curse until twenty-four hours after it's cast," he mumbled, crouching down to look the kitten in the eye. "Brother, you really need to chill out. Get this kitty some fish and take care of him until tomorrow. I'll come back then and undo the curse."

Just like that, Gabriel vanished without another word. Dean stomped his foot on the ground and looked down at the kitten... or Cas... or whatever. "What the hell are we supposed to do with an angel stuck in a kitten's body for the next few hours?"
