Dean walked into the room to find Cas sitting with the corner of a large box on his head. The opposite corner was touching the floor.
"Um what the hell are you doing?" dean asked.
"I couldn't fit in the box!" Cas said.
"Hey!" Sam said.
Dean looked up and Sam indicated for Dean to follow him. Sam lead Dean to a room out of Cas's hearing.
"Dude, what's wrong with Cas?"
"I don't think he's got sleeping down yet. He's been awake all night!"
"So this is because he's sleep deprived?" dean asked. Dean sneezed.
"Not just that!" Sam said.
A bunch of stray kittens came hurdling in as Sam opened the door a crack. They ran out to Cas where he sat bundling them in close to him. He stroked them all lovingly as they clambered over him. They curled up in the box that hung from Cas and tried to sleep.
"Oh hell no!" dean said.
Dean stormed in over to where Cas sat.
"Cas we can't have this! No cats! I'm allergic, remember?!" dean said.
"I know dean. I know everything about you. But look how cute!" Cas held up one of the kittens.
The kitten was as black and fluffy as Castiel's hair, and their eyes matched. Kevin gasped in delight and cooed at the kitten when he saw it. Kevin scooped it up and scratched it behind its ear. The kitten tried to climb up onto Kevin's head, and the other kittens started mewling at his leg. Their mama came strolling in elegantly. She let out one calm meow and the kittens scarpered over to her.
"Cas, the cats have to go!" dean said.
"But dean!" Cas said.
"Cas! The cats go or you go!" dean threatened.
"You said that before and I came back," Cas said.
"It hurt to see you go, but I can't have the-"dean sneezed. It increased his irritance.
"Dean, are you allergic?" Kevin sked.
"Yeah," dean said.
"Cas, if Dean is around cats too long it irritates his body. He could die!" Kevin explained.
Cas's eyes shot up to Dean's in concern. He seemed to think that the cats would kill him, and he unshed them out. He didn't take the box off of his head the entire time. Castiel yawned widely as he tried to walk past dean. Dean stopped him.
"Box!" he said.
"Dean I-"
"Take off the damn box!"
Reluctantly Cas took off the box. One kitten looked up at Dean. The kitten playfully pawed at dean's watch. Dean gave Cas a look. Cas looked guilty.
"How did that get there? I put them all outside!"
"Sam!"
Dean handed Sam the box. Sam placed the kitten outside with the others. Instantly the kittens ran back in again. Kevin and Sam spent twenty minutes chasing rouge kitten outside again. Dean stood face palming and sneezing the whole time.
"Cas let me make this very clear. NO. CATS!" Dean said clearly, "understand?"
Cas nodded softly. Dean hooked the box over Castiel's face.
"Bed. Now!" Dean said.
Kevin wolf whistled.
"Don't even!" Dean said.
Sam was grinning though. He gave Kevin a pleased nod and ruffled his hair affectionately, the way dean did to him growing up.
