Hey! This is my fourth Cats fanfic, so I just gotta say that I don't own 'Cats.' This story revovles around Munkustrap, the Rum Tum Tugger, and Macavity, who, to me, are the sons of Deuteronomy. All of them have slash relationships that you'll see with Misto+Tugger, Alonzo+Munk, and Tumbles+Macavity. It's not really a spoiler alert cause you find out about the relationships early on and you mostly see how they develop instead of who something develops with. So thanks for reading and enjoy!

The small kitten with the growing maine covered his ears and closed his eyes, trying to keep out the yelling.

"You can't do that!" shouted his older brother.

"Says who?" asked his oldest brother.

"Says dad."

"Because no cat has ever disobeyed their parent."

"Why do you have to be so stupid?"

"I'm not stupid!" roared the eldest brother.

"Well quit acting like it!"

The youngest brother opened his eyes when he heard the middle brother cry out in pain. He looked to his oldest brother to see a look of guilt as he glanced at his paw. The guilt diminished and turned to a scary look in his dark eyes. He swiped his paw over his younger brother's face again. "I'm not stupid," he hissed and walked away.

The young kitten looked at his brother. "Munkey?" he asked. "Are you okay?"

"I'm fine Tummy," said Munkustrap, trying to hold back the tears that came with the pain from the two wounds on his face. He let out a shakey breath. "I don't understand why he has to be that way."

"Well, you did call him stupid."

"He was breaking the rules."

"You break the rules."

"He was breaking one that's bigger than staying up past bedtime, Tummy."

"What was it?"

Munkustrap looked to his innocent, younger brother. How am I suppose to tell him our brother was was talking with cats he shouldn't have? It's treason to talk to them, Munkustrap thought. "I'll tell you when you're older."

Rum Tum Tugger pouted. "You're only a few months older than me, you know? Don't act like you're a tom. I don't get why you treat Macky like that. He's a tom and you're not so you shouldn't talk to him like that." The young kitten walked out like his oldest brother, his words stinging Munkustrap more than his wounds.

It hurt Munkustrap to see that his favorite brother's favorite brother wasn't him.

"Macky?" Rum Tum Tugger asked, entering his brother's den.

Macavity looked to his favorite brother and sighed, feeling guilty at having to expose his innocent brother to violence. "Hey Tummy," Macavity said. He never called him Tummy in front of the other toms since he had only recently become one and still was looked at like a kitten. Though he called him it when they were in private, since he still did act like a kitten.

"Why are you so mean to Munky?"

"Because he's a jerk."

Rum Tum Tugger sighed. "You're both jerks."

Macavity smirked. "It's not like I don't feel bad. He is my brother and I do love him. It's just..." He sighed. "Growing up, it changes us. We turn in to cats who get too serious and put pressure on ourselves too much." Macavity petted his brother's growing maine. "Look, Munky's gonna do great things with this tribe and he's gonna be respected a lot more than you and he's gonna get more attention. That also means he's going to be put under pressure more and isn't gonna be as happy. So can you just promise something?"

Rum Tum Tugger nodded at his older brother.

"Just do what you want. Don't let others tell you what to do and don't make things easy on them. The majority of these cats deserved to be mistreated." A scary, sinister tone grew in his voice at his last sentence, but eased up with his next. "Also, always question things. Questions yourself and things around you. Don't let anyone tell you that your opinion or interest in something isn't right. It's good to be curious. Try new things. See new things. Feel new things." A sad look crossed his face. "People will tell you that you shouldn't feel this way or do this, but don't listen to them. Don't let them influence you. I know I shouldn't have..."

Rum Tum Tugger smiled. "I promise to do all that, Macky."

Macavity smiled. "Good." Then he stood up and opened his makeshift window. "Now, dear brother, I must leave you."

"Where are you going?"

"I need to leave. I can't stay here anymore. Tell Munkustrap I'm sorry and that I love him. Tell Dad that, too."

"When will you come back?"

Macavity frowned. "I don't know." He turned his back on his younger and favorite brother, not wanting it to ba harder than it was.

"Macky!" Rum Tum Tugger called, but he was too small to look out the window. He ran out of the den, but Macavity wasn't there. "Macky," he whimpered, already missing his brother.

Macavity hid from his brother until he knew it was safe to come out. He snuck along through the crevices of the Junkyard, wanting to not be seen.

"Eep!" cried a kitten when Macavity accidentally stepped on its tail, not seeing it.

"Shit," he mumbled, but once he saw it was kitten he watched his mouth. He bent down and looked at the kitten hidden in the shadows. He had seen the kitten which was newly born, but had a hard time trying to remember its name. He hardly remembered any of the kittens' names. "Uh, what're you doing out here?" he asked.

"I-I was...hunting for mice," said the little white tabby with brown patches and long fur on the head with doughy eyes and a naturally pouty mouth.

"Why? Do your parents not feed you?" Macavity mentally slapped himself. I really need to get going.

"They do...I just wanna learn to be a good hunter."

Macavity nodded. "Let me help you out. There a crevice clear in the back of the Junkyard, the right side. Underneath an old milk crate there's a bunch of already dead rats there that I've caught. I don't need them anymore, so you take them. As for actually hunting - be patient and don't look for rats. Wait in a place until they come by and then pounce from your back legs."

The kitten smiled adorably. "Okay!" he chirped. "Thanks."

"No problem." Macavity stood up, ready to head out, but he knew he wouldn't be able to focus without knowing the kitten's name. "What's your name?"

"Tumblebrutus," said the kitten.

"Tumblebrutus. Nice." Then Macavity headed out, leaping over the gate of the Junkyard into the mysterious night.

Rum Tum Tugger looked at himself in the mirror the next day, trying to see a resemblance to Macavity and Munkustrap. He sighed. He really missed his brother.

"Tugger," said his father frantically, coming in to the room. "Where's Macavity? I can't find him anywhere."

"He left," said Rum Tum Tugger.

"Where to?"

"I don't know. He just went out through his window last night. He told me to tell you he's sorry and that he loves you."

"What? Did he say why?"

"Yeah."

Deuteronomy came closer to his son. "Well what did he say?"

"I don't think it's my right to tell you," Rum Tum Tugger said.

Deuteronomy's brow furrowed. "Tugger, why are you being difficult?"

He started to walk out of the room, saying on his way out, "Because I'm the Rum Tum Tugger."

Munkustrap overheard the conversation between his brother and father. Macavity? Gone? He went out and followed his brother. "Tummy," he said grabbing his brother's paw.

"It's Tugger," said the Rum Tum Tugger, yanking his paw away.

Munkustrap frowned at his brother. "What did Macky say?"

"Stuff, Munk," said Tugger, starting to walk away again.

Munkustrap grabbed his defiant younger brother and shoved him against the wall. "Tell me!"

"Fine! He said he loved you and that he's sorry. He said he couldn't stay here anymore and that's it."

"What did he say to you?"

"None of your business!" shouted Tugger shoving his brother away.

Munkustrap clenched his jaw. "What do you mean none of my business? I'm pretty certain my brothers are a part of my business."

"He made me promise him something, but I don't have to tell you."

"Damnit, Tummy!"

"Tugger!"

"It doesn't matter!"

"It does to me!"

"What is going on?" roared their father. "Why are you fighting?"

"He's being immature," mumbled Munkustrap.

"He's being too mature for his age," said Tugger.

"Both of you need to stop this," said Deuteronomy. "Both of you need to go to your rooms and stay there until we find your brother."

"You're not gonna find him," said Tugger.

"You don't know that," said Munkustrap.

"I do, too! There's a reason he always won at hide-and-go-seek!"

"What do you mean?"

"I don't have to tell you."

"Rum Tum Tugger," said his father furiously. "Tell me this instance what you know."

Tugger frowned. "I don't know what it is, but he just vanishes. He can disappear into thin air."

Deuteronomy and Munkustrap looked at Tugger, awe-struck.

"He said he has magical powers, cause he was born at midnight. He says that's why he was sick, cause he bottled up his magic but then that day when he seemed to become ten times better somehow, he said that's the day he unleashed his magic."

Munkustrap remembered that day a few months ago. Macavity had always been sick as a kitten, but then one day he was leaping all across the Junkyard, like new life and energy had consumed his body. It was miraculous. He also remembered the time when Munkustrap had cut his leg on a piece of glass and Macavity healed it quicker than Jennyanydots could do. It seemed...magical.

"It doesn't matter, though," said Tugger. As he ran away, he yelled, "Macavity's gone and he's never coming back!"

Though all three of the brothers knew, he'd eventually return.
