A/N: Heeeeeeeeeeere's Andrea! I've been looking forward to this chapter for a while...

Disclaimer: Nope, but I own Andrea!

"Hey, Guys!" April greeted cheerfully as she walked into the Lair with a small, four-legged creature following on her heels. "Guess what I found!"

"I'm taking a wild guess here, but I'm gonna say some sort of cat..." Raph responded while taking his eyes off his magazine for a second to see the small creature.

"Sort of…" Before she could say anything else, the small creature ran past her and Raph and ran in the area of the lab. "Hey! Andrea, come back!"

"'Andrea'?" Leo questioned as he walked into the room and grabbed the creature when it got near him. "Where'd he come from?"

"Uh, I found her near my apartment. My aunt won't let me keep her, but I didn't think she would be able to find a proper home in the city, so I talked with Splinter after our last training session, and he said it was alright if she stayed here." April then was about to add something, but Andrea suddenly let out a loud hiss, causing Leo to drop her. "She's also a little finicky…"

"Well, that would've been helpful to know!" The leader of the group turned to go after the creature, but Andrea definitely was able to use her size as an advantage and squeezed into the lab door right as Leo noticed something. "Uh…April…is that cat a mutant?"

The ginger blushed slightly at the revelation, and even Raph was paying attention now. "I just found her like that. I-I didn't see the mutation, and for all we know, she could have been a mishap from a breeder."

"…cross-breeding cats and dogs?"

"See what I mean when I say humans are crazy?"

Mikey watched in curiosity as Don poured the solution from one beaker to the next. It actually was kind of interesting to see his genius of a brother work, plus they currently had a deal going on where if Mikey could stay quiet for the duration of this experiment, Donnie would do something with him.

Of course, something else had to interrupt.

A small, furry something.

"Uh, Donnie…what is that?"

The creature on the lab table that had knocked down a beaker looked mostly cat like, but its ears flopped oddly, and its tail looked almost like a fox's with the way it fluffed out, though it still was able to stick straight up. If he had been closer, he would've been able to tell that despite the tabby cat pattern on its fur, it was only fluffy on the tail and back, whereas the rest of the fur was more course and almost waterproof. [1]

"Uh, looks like a cross between a Felis catus domestica and a Canis lupus familiaris," Don answered as he picked Andrea up, earning a small purr. [2]

"Uh…"

"Combination of a cat and a dog. I wonder how it got into the Lair…" As if to answer his question, April and Leo came in, both sighing in relief at seeing the cat/dog wasn't causing too much damage.

"Oh, uh, I see you've met Andrea…" April sighed as Donnie pulled the hybrid closer to his plastron. "I'm glad she likes you at least…"

"Eh, Leo's never had luck with cats," Mikey quipped as he slid off the counter he was sitting on and went to get a better look at Andrea, earning the same reaction as Leo. Luckily, Donnie had good enough grip on her that his jump didn't cause him to drop her, but she still let out a bark of surprise.

"And neither have you, Mikey," Leo retorted with a grin as he watched his second youngest brother gently pet the…cog? Dat? They'd have to come up with that later.

"Well, she's gonna be staying here a while...Don't worry, Splinter approves!" The turtles let out a small giggle at her slight panic, and Leo shot her a grateful smile.

[1] Growing up, I had a tabby cat who was a little sweetie (when she was being social), and all but one of the dogs I've lived with had this fur that was meant to be mostly waterproof (think black lab…especially since that's what I was thinking of!), so I tried to take elements from both to create Andrea here. She may show up in another story…

[2] Considering he knows the scientific name for a salamander, I don't think it's too farfetched he knows the scientific names of a cat and dog.

A/N: Hehe...Love that creature! I came up with her forever ago, and she just kind of fit...I do have other TMNT fics in progress, so she may sneak into one or more of those. ;)

Question: Would you rather the last chapter end on a fully complete note, or have it be slightly open-ended, but I'd be doing a one-shot series based on this as well? I'll put this as my profile poll, and it'll be open for the weekend. You'll have until then to vote.

Love y'all!
