Two Cats in a Cradle

Thanks to all the people who read and liked my story 'Harry Potter and the True Dark Lord'. Unfortunately, I have decided to put that story on hold whilst I attempt the challenge found on WhiteTigerWolf's Forum. The challenge that I am going to attempt is about what could happen if, when Hermione made the Polyjuice Potion in the second year, what if she wasn't the only one to have cat hair in her potion. The requirements of the challenge are listed below.

Requirements:

-Must be Harry/Hermione

-Harry and Hermione must both drink Polyjuice potion contaminated with cat hair

- The transformation must be permanent

-If Harry and/or Hermione become Animagus, it must be a feline

- At some point (it doesn't have to be immediately after their transformation) Hermione must go into heat

- Harry and Hermione must be provided with a means to hide their transformations from others

- Harry must spend summers with the Grangers

- Harry and Hermione must learn to fight in their "new" bodies

- Cream and/or milk and fish must become beloved food of Harry and Hermione

- Harry and Hermione must both be wary of Lupin at first (they're part feline and he's part canine after all)

- Harry and Hermione must gain the ability to communicate with cats, and be able to speak to each other using this ability

Recommended:

- Lemons

- Kittens! Although I should probably clarify and say Harry gets Hermione pregnant at some point

- Sirius declared innocent

- Kittens, this time I'm being serious. Hermione and Harry adopt a real kitten (or cub if you want to use a bigger feline) to raise.

- Mentor Snape

So as you can see, it's quite a challenge, and I can only hope you enjoy it.
