/Later, in the Gryffindor common-room/ "This is interesting."

"What's interesting?" Harry asked, looking up from his game of chess with Ron

"We've got tomorrow off, which gets us into the weekend. To put it simply, we've got the next three days free before we begin classes." Hermione said, staring at her schedule in puzzlement.

"Awesome!" Ron said. "Checkmate."

"Is there a specific time we need to be up?" Tammy asked from where she was petting Crookshanks on a couch.

"Nope. Well, not really. You'll be fine if you're up by 6:00 when we've got class. When we don't have class, sleep as long as you want." Ron said.

" Thanks Ron. I'm going to bed." Tammy stood up and headed off to the girls' dormitories.

"I think I'll do the same. G'night guys." Hermione followed the other upstairs. After another game of chess, which Harry lost, the boys went to bed as well.

/Saturday/ There was a party going on in the common room; a very noisy party. Normally, this wasn't a problem. With Tammy around, it was. Within the first half-hour, she'd nearly gone insane from the noise. Hermione was busy elsewhere, so Ron and Harry took it in turns to watch the girl, who had found sanctuary in the boys' dormitory. After about four hours, both boys stayed in the dorm, watching as Tammy, affectionately called Kit by Hermione and the two of them, explored their turf, then played quietly with a ball of string she had, and even managed to get the boys to play Cat's Cradle with her for a while. After making sure that Kit was quite tangled up in the string, Ron and Harry chatted quietly with one another, sitting on Ron's bed.

"It's so funny how she can act so much like a cat and no one really notices." Ron commented.

"Yeah. Still, people around here see what they want to see. If they think of Tammy as a normal human girl, then that's what she is to them. After all, you and Hermione saw me as a friend and a fellow wizard, rather than a hero."

"Am I interrupting something?" Neville peered in the doorway.

"No, you can come in." Harry responded. Neville did, opening his trunk and removing a shallow plant dish. It had what seemed like grass in it, and some small yellow flowers. He placed it carefully on the stand next to his bed. Tammy, who had managed to detangle herself, walked over and sniffed delicately at the flowers.

"These are lovely Neville." she said, smiling. Neville blushed at the praise, and plucked a delicate bloom, handing it to the girl with a graceful flourish that left Harry and Ron in shock. "Catbalm, right?"

"Yeah. You know what it is?"

"Uh-huh. There was a lot of it in the woods near my house."

"I'll leave you guys alone now." Neville said, and backed out of the room, having watered his plant.

/15 minutes later/ "Hey, Harry."

"What is it Ron?"

"Is Kit acting a bit…I dunno…a bit odd?"

"Now that you mention it, yeah, she is. Like she's really hyper or something. I wonder wha- Agh!" Tammy leaped up, grabbed Harry's hands, and bounced away, leading him in a wild dance around the room. Ten minutes later, she was asleep in a ball on the floor.

"What caused that?" Ron asked, looking at Harry, who was sitting on his bed, looking shocked and exhausted.

"I don't know, but I have an idea." He got up and went back downstairs. It took him a few minutes, but he found Neville. "Oy! Neville! I need to talk to you!" Neville nodded, and the two retreated to the stairwell so they wouldn't need to yell to hear each other.

"What is it Harry?"

"What are the properties of catbalm?"

"Well, it's used both in knock-out potions and ones to give extra energy, and it's got an interesting effect on cats."

"What about cats?"

"After they smell it, they act really energetic and playful for between 15 to 30 minutes, then they fall asleep. Depending on how long the exposure is, they might sleep for a few hours, a few minutes, or for a full day. It takes almost a full day of exposure to make them sleep that long though."

"Thanks. Neville, would you mind moving your plant for the night?" Harry pulled out his wand behind his back and cast a quick charm that made his eyes water. "It's bothering my allergies." Sure, it was a full-out lie, but it worked.

"Oh, sure!" Neville hurried to obey. When Harry got back upstairs, Tammy was running around, obviously under the influence of the catbalm again. Harry explained the situation to Ron, then climbed into bed (he was already wearing his pajamas) and watched to make sure that Kit didn't get herself into trouble. He was actually starting to fall asleep when his mattress shifted under the application of extra weight.

"Huh?" Harry blinked, and realized that Tammy was making herself comfortable on his bed. Right next to him, as it happened.

"Kit, what are you doing?"

"Going to sleep. What does it look like?"

"In my bed! With me!" Harry hissed, appalled.

"Where else? With Ron? I'm tired, and that party isn't showing any sign of slowing." Tam growled, baring her teeth, which were still sharper than normal, even if she looked fully human right now.

"Okay, fine. Let's just try to not make this a habit, okay?"

"Okay. G'night Harry." Tammy pulled the blankets over herself and shut her eyes. Swearing under his breath, Harry rolled over so that his back was to hers, and fell asleep, dreading what would happen if someone took the current situation the wrong way.

/Morning/ "Harry? Um…you might want to wake up now. Like RIGHT NOW!" Harry rolled over and ignored Ron. Biiiiiig mistake.

"Jeez Harry! Just waitin' for a chance to get at the new girl?"

"What are you talking about?" he growled, notbothering to look up.

"I mean you and Tammy sharing a bed. From what I can see, you certainly enjoyed yourselves." Seamus said, prodding impatiently at Harry's shoulder. After several minutes of futile attempts at ignoring this, Harry opened his eyes, to come face to face with a sleepy-looking Tammy. They were nose-to-nose, literally, all curled up together.

"Eeeep!"

"Aaaagh!" The pair jumped backwards, away from each other. Both overshot and fell off opposite sides of the bed. Harry, with a mumble of 'don' wanna ge' up', climbed back into bed. Tammy sprang up, stomped over to Seamus, hissed at him, and stalked out of the room.

"Sheesh. What's her problem? Harry? Harry? Oh, never mind." It was no good trying to talk to the boy; he was asleep again.
