Dr. M'Benga had finished examining Spock, then Scotty picked Spock back in his arms, but Spock kept pawing him to release him from his clutches.

"What's wrong, Dr. M'Benga," Captain Kirk worried.

"Besides being a cat, nothing; all of his body functions are working the way they should." Dr. M'Benga answered.

"How did Spock turn into a cat, though; how?!" Captain Kirk ordered.

"I can't answer that, Captain; there's absolutely no disease in existence that causes a man or Vulcan to turn into a cat just like that."

"He can't just stay like this,"

"I don't know what else you want me to do."

"I think that Riker guy had something to do with this." Scotty answered.

"We've gotta find Riker; maybe he can explain what happened." Captain Kirk ordered.

Dr. M'Benga nodded.

They heard a familiar voice talking to someone in another room.

"It's Dr. McCoy," Scotty cried.

"Hide; McCoy can't see what's happened to Spock. If he does, he'll stop vacationing, and he needs this time off, bad." Captain Kirk spoke, anxiously.

Scotty pointed to a closet in the corner of the room. Him, Captain Kirk, and Spock went into the closet, closed the door and stayed put, until Dr. M'Benga would tell them Dr. McCoy was gone.

Dr. McCoy entered the room wearing a suit and tie. His suit was gray, and his tie was dark blue; he looked very sharp and official.

Dr. M'Benga whistled.

"Man, Doc; you clean up real good, there!" Dr. M'Benga chuckled.

Dr. McCoy laughed.

"Oh, I'm just going dancing tonight, nothing much. Atticus, thank you so much for telling me to go on break; I can't remember the last time I felt this good!" Dr. McCoy cheered.

"Well, I'm glad just to get that stress relief off of you. I thought you were on the verge of a breakdown, a while back." Dr. M'Benga answered.

Dr. McCoy smiled.

"Well, thank you; I'm reading, writing, dancing, swimming, watching baseball, getting wonderful amounts of sleep, and I have you and Jim to thank for that!" Dr. McCoy beamed.

Captain Kirk felt a pang in his chest, feeling horrid from hiding from Dr. McCoy, but if he saw Spock, he wouldn't go back to his vacation, until Spock was back to normal, or return to work, at that. Dr. McCoy was under so much work and stress lately, he couldn't stand watching Dr. McCoy get so worn out and emotionally weak.

"I'm glad you're enjoying yourself, Leonard." Dr. M'Benga spoke, with a smile.

"So, how's work going on, here?" Dr. McCoy questioned.

"Uh uh; no, Leonard. That's exactly why you're on this vacation break; no work whatsoever. That means no actually work and no talking about work, either."

Dr. McCoy sighed then smiled.

"Guess you're right, Atticus; talking about it would probably make me start wondering whether or not I'm needed back for work." Dr. McCoy answered.

"Exactly," Dr. M'Benga replied.

Dr. McCoy continued to smile, when a black cat, Spock, ran out of the closet, making a very angered meow noise. Captain Kirk and Scotty then ran out of the closet, not knowing what else to do.

"Spock, Spock, Spock, here kitty!" Captain Kirk cried.

"Spock, here kitty, kitty, kitty Spock," Scotty called.

The two men left Dr. McCoy gaping at the doorway, wondering what on earth was going on with those two, and why they were calling a cat Spock. Dr. McCoy walked out, wanting to know what was going on…now! Dr. M'Benga sighed, knowing what was coming next.

Spock was standing up in Dr. McCoy's chair, hissing at Captain Kirk and Scotty from getting anywhere closer to him.

"Oh, come on, Spock; it was an accident." Captain Kirk pleaded.

"I didn't mean to step on yah tail, Mr. Spock." Scotty cried.

Spock hissed, violently, warning the two men to back off. His tail and whole body was puffed up, glaring at the two men angrily.

Dr. McCoy came out and glared at the two of them.

"What's going on, here," Dr. McCoy growled.

Spock hissed louder at Scotty, then gave an angry meow and hissed, again.

Captain Kirk looked up and sighed, feeling horrid; this was it…it was over…Dr. McCoy would no longer want to be on vacation after this. Captain Kirk let a huge breath of air out and looked up sadly at his dear friend.

"I'm sorry I'm gonna ruin your vacation, Bones." Captain Kirk answered, sadly.

Dr. McCoy gaped at Captain Kirk.

"Jim, what do you mean," Dr. McCoy gasped.

"Mr. Spock has turned into a cat somehow, and we're trying to figure out how it happened and get Spock back to his normal self…so…go ahead and go put back on your Starfleet uniform…I know you won't be convinced to continue vacationing, until you know Spock's alright." Captain Kirk answered.

Dr. McCoy gave a small smile.

"What," Captain Kirk spoke, sadly.

"Jim, I'm not gonna stop being on vacation." Dr. McCoy spoke, friendly.

Captain Kirk looked up, surprised.

"But…but…Spock is," He was cut off.

"I know Spock's condition, but you told me what was going on instead of hiding it from me for so long. I'm gonna continue being on my vacation, but I think there's something I can give you to help you two out a little bit." Dr. McCoy spoke, kindly.

Captain Kirk smiled.

"Thanks, Bones; I'd really appreciate that." Captain Kirk spoke, with a smile; he hadn't ruined his best friend's vacation leave, after all.

Dr. McCoy walked over to his med bag sitting on his desk, and he looked through it, trying to find something. He pulled out a tiny purple pill and held it in his fingers.

"What's that," Captain Kirk questioned.

"It's a medicine; it'll be able to trigger the part of Spock's brain, so he can communicate with you, and you two will be able to understand what he's saying." Dr. McCoy answered.

"Thank you, Bones," Captain Kirk answered.

"We can't give it to Mr. Spock, look at him, Captain!" Scotty cried.

Spock hissed viciously at the two of them.

Dr. McCoy smirked and walked over, then knelt down next to his chair next to a frazzled Spock. Spock looked over at Dr. McCoy and stopped hissing. Dr. McCoy smiled and gently started petting Spock's head. Spock began purring, and Dr. McCoy held his other hand out with the pill in it. Spock sniffed it, assuming that Dr. McCoy wanted him to take this medicine for some reason, and ate it, then continued purring, as Dr. McCoy continued petting his head.

Captain Kirk and Scotty stood there, amazed.

"Bones…you actually got Spock to purr!" Captain Kirk cried, happily.

"Well, it may still be Spock, but all cats loved to be pet, just some are particular with being held." Dr. McCoy answered.

"I know that's true," Scotty cried, rubbing his arm from where Spock had scratched him several times, trying to get down out of Scotty's arms. Dr. McCoy walked over to Scotty, pulled up the back of his shirt, and treated the scratches with bacterial cream to kill any germs entering or already in Scotty's cuts. Dr. McCoy then gently placed a band-aid on Scotty's shoulder, then put his shirt back down the way it was.

When Dr. McCoy finished washing his hands, he walked back over to his two best friends, and his best Vulcan friend, who was now a cat, at the moment.

"Thank yah, McCoy," Scotty spoke, with a smile.

"No problem, Scotty; that's my job, and it's worth all the stress, when I get results such as one of my patient's is gonna be okay." Dr. McCoy answered, friendly.

"Spock…can you hear us," Captain Kirk questioned.

Spock meowed, then again, but it sounded more to have a word fill into it. After several times meowing with words mixed in somehow, Spock finally was able to speak.

"Captain," Spock spoke.

"Spock, you can talk, again!" Captain Kirk cried, with a smile.

Dr. McCoy smiled.

"I'll leave you three be; I've gotta dance to get to." Dr. McCoy spoke.

"Have fun, Bones," Captain Kirk spoke, smiling.

"I will," Dr. McCoy answered back.

Dr. McCoy walked off out of Sickbay to go to his dance, and Captain Kirk and Scotty began talking with Spock…who was now just an ordinary cat.

"Mr. Spock, what happened to yah?" Scotty cried.

"I'm a cat, Mr. Scott; my appearance is enough proof to be logical." Spock answered.

"I meant how did yah get turned into a kitty cat?"

"Riker,"

Captain Kirk gaped at Spock.

"Riker," Captain Kirk gasped.

"I knew he had something to do with it!" Scotty cried.
