Chapter 1

His heart hammered in his chest as Harry stared at the potion vial in his hand. Excitement filled him as the sixteen year old gazed up at his transfiguration professor with unsure eyes as he uncorked the glass vial. Emerald eyes gazed into aged blue eyes asking the silent question that played across Harry's mind.

"Yes Mr. Potter, that is the real thing, even though normal students do not learn about becoming an animagus until the last term of seventh year after their NEWT's I have decided to make an exception for you," Professor McGonagall said as she gave Harry a pointed look. "With the way the Wizarding World is at this moment and how...how certain people have been keeping secrets from you I decided to step in."

Harry nodded his head, his throat going suddenly dry as he did his best to stay calm. This was the very last thing that he had expected from his Professor when she had asked him to come to her classroom after the evening meal, without Hermione or Ron.

A frown appeared on his face as Harry he stared at Professor McGonagall. "You know something...something important that I do not."

"That is correct Mr. Potter and I hope that this evening I can change that," Professor McGonagall said stiffly as her eyes flashed away from Harry to the locked and heavily warded classroom door before returning to Harry. "There are a lot of things going on, if you knew the truth about what was really going on within this school your head would spin!"

"And so this is a big hint from you for me to learn just what is being hidden from me while also making sure the likes of the Headmaster does not find out," Harry stated dryly as he easily caught Professor McGonagall's surprise. "I am not as dump or oblivious as everyone makes me out to be. I notice a lot more than I normally do; sometimes it is like there is a little voice in the back of my head telling me things."

"That is good news, there is still hope for him then," Professor McGonagall whispered softly confusing Harry. "Drink up Mr. Potter, while we do have several hours together we do not have all night before the Headmaster decides to check in on your progress."

Nodding his head Harry lifted the potion up to his lips. His mind swam with different thoughts and ideas though all of them were connected to a single thought. What would his animagus form be? Thoughts of his father and Godfather flashed though his mind only for all thoughts to be wiped clean as the potion rested on his lips.

'Well here goes nothing, I hope Professor McGonagall has something ready to get rid of the normally horrid taste that all potions have' Harry thought as he took a deep breath and swallowed the potion in one go.

Professor McGonagall watched with baited breath as her young lion swallowed the potion. She knew what the boy would transform into, it was so obvious to her from the boy's mannerisms and how her own animagus form called out to her ordering her to look after the small orphaned kitten. Hope and dread welled up inside of her as she watched the vial fall from Harry's hand to the floor with a small clatter as the potion began its work.

'Please let this work, please let mine and Poppy's plan work' Professor McGonagall silently thought as she watched Harry's body begin to show signs of transformation. 'This is the only way we can tell him without Dumbledore's spell interfering. Hopefully the spell will at least let me tell him some information if what I think will happen does.'

With trained eyes Professor McGonagall watched as her student's body began to twist and reshape and shrink. The once smoothed skin changed into fur, human ears disappeared only to be replaced by feline ears and a long feline tail appeared. Relief radiated from her body as Professor McGonagall watched the transformation finish. A small smile appeared on her face as she looked down at the small creature on the floor in front of her.

Where Harry had once been was now a very small and nervous looking kitten. Out of proportion body parts easily told Professor McGonagall that her young student's animagus form was very young and had not hit its growth spurt. A soft chuckle escaped her lips as Professor McGonagall watched the cute button nose twitch slightly as if trying to prevent a sneeze.

"Congratulations Mr. Potter, your animagus form is a house cat like mine. It seems that stubborn personality of yours along with your love of fresh milk has shown face," Professor McGonagall stated as she pulled out her wand and with a quick wave of it a mirror appeared on the floor for Harry to look at his new form in. "If you would like to take a look in the mirror you will notice something very special about your animagus form."

As she watched Harry slowly standing up as he tried to get used to standing on four legs Professor McGonagall let out a soft sigh. She could feel the sharp angry tug on her magic, reminding her of the horrid spell that Dumbledore had placed on her.

'It looks like I am pushing my luck, I need to be more careful about how I tell Mr. Potter this' Professor McGonagall thought as she watched Harry shakily make his way over to the mirror, falling over and stumbling cutely several times. 'Well at least telling Mr. Potter the species of cat that is his animagus form and suggesting that he should research it by himself will not be a problem.'

Totally unaware of the dilemma going through his transfiguration professor's mind Harry finally made it to the mirror. Even though it had only been a short trip his whole body felt as if it was about to collapse from exhaustion. Not wanting to let all of his hard work go to waste though Harry looked into the mirror only to freeze at the strange creature in front of him.

'W-What happened? Did something go wrong with the transformation?' Harry thought frantically as he stared at himself in the mirror, his eyes growing wide. 'I look like two cats stuck together! It's as if someone took a pure black cat and cut it in half from head to toe before doing the same to a brown cat and glued the two halves together to make me!'

"You Mr. Potter are a rare type of cat," Professor McGonagall said, cutting Harry's inner rant off. "Your breed is called a Chimera cat, it is where two non-identical twins merge together in the mother's womb, and this means they can be male, female or hermaphroditic."

Harry stared with wide eyes at Professor McGonagall as he soaked up all of the knowledge she had to give him. His mind buzzed busily as everything she said sunk in. Unknown to him though his Professor was doing her best to fight off the spell Dumbledore had placed on her.

"The two books I brought with me at the start of this private lesson will hold all of the information that you need," Professor McGonagall stated as she tricked the spell into thinking, she was simply giving the student homework. "As homework I would like for you to take the books and read them both in private. The whole book for the purple covered one and the section on your Chimera cat animagus form for the blue covered one. I expect you to do this in private without anyone, even Mr. Weasley and Ms. Granger, as this is something a private affair between us and I do not need them demanding that I teach them to become animagus' too."

As Harry nodded his head a relived sigh fell from Professor McGonagall's lips. Reaching into her robe pocket she pulled out her wand and cancelled the spells she had protecting the room and banishing the mirror. Hearing a questioning meow Professor McGonagall gave her student an oddly soft look as she put her wand away.

"Do not worry, the potion should ware off within the next two to three minutes, afterwards you are free to leave the classroom with the books. Though I ask that you stay for a few minutes as going from four legs and a tail back to two legs; it can be a bit disorientating for the first few times."

Harry bobbed his little kitty head up and down in agreement making Professor McGonagall smile. Opening her mouth to speak Professor McGonagall found herself cut off as a sudden short beep came from behind them.

'I wonder what that sound was from' Harry thought only to gulp nervously when he spotted the stormy expression on Professor McGonagall's face. 'Whatever it was it seems that it has gained the Professor's anger.'

"Please excuse me Mr. Potter, it seems that the Headmaster is requesting a floo call with myself, most likely about how your first animagus transformation has gone," Professor McGonagall said stiffly before turning and heading towards the door that led to her office. "I will see you in class tomorrow Mr. Potter, and please remember the books."

Harry let out a meow that he hoped sounded like a 'okay' and a 'good bye' before Professor McGonagall quickly disappeared into her office slamming the door behind her. A few seconds later another beep echoed throughout the classroom making Harry assume that Professor McGonagall had answered the floo call.

'I wonder why Professor McGonagall is so angry about getting a floo call from the Headmaster for' Harry thought as he tilted his head to the side. 'I wonder when I will become a human again, I really want to learn about these Chimera cat...I wonder how this will affect my animagus form.'

As if answering Harry's question Harry's whole body was suddenly covered in pins and needles. Just like moments ago Harry transformed though this time going the opposite way and going from kitten to human. A few seconds later Harry found himself standing on shaky legs feeling as if he was missing several key parts of his body.

To Be Continued...

I have no idea where this plunny came from, it is going to be a very weird one but I hope you all enjoy it. Depending on how things go with this story I might make a sequel to this story though it will be a crossover.
