"God dammit Jim! What the hell happened now?" McCoy exclaimed as he glared at the trio in front of him that had just stepped into his Med Bay. Jim was gritting his teeth while Spock remained stoic and Harry blushed in mortification, utter embarrassment radiating from them. They were physically fine except for a tiny little change; atop their heads were pairs of adorable cat ears and twitching behind them were tails. It didn't take a genius to put two and two together, the transporter had malfunctioned again. It wasn't often that it did, but sometimes it happened due to certain planets and energies they came into contact with.

Teddy blinked curiously from his perch on one of the bio beds, "Dad looks cute!"

Harry blushed even more and held in the urge to hide his face, this was just too much! Grinning slightly Jim agreed, "You're right, he does look cute… well more so than usual."

"I will hurt you!" Harry exclaimed his tail bristling. McCoy snorted holding a hand over his mouth to muffle his chuckling. Jim's grin grew but he wasn't allowed to say more as Spock gave him a stern look. Right now wasn't the time for them to be joking, they had to figure out how to return to normal. Focusing his attention on McCoy, Spock explained, "It seems that there was some interference with the planet's atmosphere was we were beaming up and the result is our current state."

Shaking his head and muttering about the dangers of transporting, McCoy immediately guided them to some bio beds instructing them to sit. Whipping out his tricorder from god knows where, he immediately began to scan them to ensure that there were no other nasty little surprises. But it seemed luck held out as he reported that besides their obvious changes, there was nothing else wrong with them and it was a relief for them.

"So how exactly are you going to fix this?" McCoy questioned, a taint of irritability still in his voice as he put his supplies away. Jim shrugged, his tail swishing lazily, "Scotty and Chekov are working on it. So we're stuck like this for a while."

"Only you," McCoy muttered. The blond just grinned while Spock and Harry hopped off their bio beds straightening themselves. Harry automatically leaned down and picked up Teddy, sighing as he allowed his son to play with his ears. Between his and Jim's luck, he shouldn't have been too surprised by their mishap. Put two people who both have giant targets on their backs together and watch the sparks fly as the universe has its fun.

"Well… I suppose it could have been worse," Harry tried to reason adjusting his hold on Teddy. McCoy snorted while Jim nodded happily, "Yup! We could have been turned fully into cats and then you probably would have been forced to chase us around to catch us."

"Like I don't do that enough already," the Southern doctor complained. Teddy giggled greatly amused by the situation while Harry just shook his head fondly. He nearly jumped in surprise when he felt something curling around his tail and glanced back, surprised to see Spock's twining with his. A flush warmed his cheeks as he risked a glance at the Vulcan who was stoic, appearing as if nothing was out of sorts. Debating for a moment, Harry decided not to really bother with it. It wasn't like Spock was hurting him and it was kind of sweet in a strange sort of way. But of course Jim noticed and pouted playfully, "No love for me?"

"You're too far," Harry retorted without pause. Grinning Jim hoped off his perch and immediately walked over pulling his lovers close while his own tail curled with theirs. McCoy's grumbling about getting a room was ignored as Jim beamed happily, no doubt pleased with himself. Harry let out a huffed laugh while Spock's eyes warmed in fondness. Teddy turned his focus from Harry's ears to Jim's which the blond didn't mind, rather he seemed to be purring and basking in the attention.

"We should totally call Pike," he exclaimed suddenly.

"Jim you're going to give that poor man a heart attack I swear," Harry protested. Spock intervened, "It would be logical to contact the Admiralty and inform them that due to our condition, we will have to decline further missions until we are returned to normal."

"Guess you've got a point."

"Come on, it's not so bad. I think I could get used to this cat thing," Jim chirped looking on the bright side. Harry made no comment and allowed his lover a moment to indulge in his carefree thoughts. Sadly Jim didn't receive his wish to keep his new ears and tail despite their uses. Two days later Scotty and Chekov worked out the problem and the trio was returned to normal. But for a few weeks afterward, they could have sworn they felt the familiar twitch upon their heads or along their spines which made them occasionally take pause to ensure that they were just imaging it.

Please review! Thanks!
