English is not my main language, so please forgive my errors.

I'm writing a tale (in french) as a Christmas gift for someone I love.
The loved one is female and shes 23.

The main characters are a blue cat (female) and a black squirrel
(male). To some extend, the cat is my loved one & I'm the squirrel :)

I need ideas for a story line... Places, events, characters... Feed me with ideas!

If possible, it would be great to have some links to literature forums
where I can get similar help from a community of story lovers.

Comments welcome!

Interesting choice of characters, which seems very important.  I
expect that you would like them to have personal characteristics of
you both, something you will have to supply.  I've got no story line,
just a couple of ideas:
squirrels are providers, gathering and storing nuts in the fall to
have food in the winter.  Cats do a lot of grooming, licking their
fur, something Blue Cat could do to Black Squirrel.  They could
exchange signals with their tails, and maybe eventually intertwine
them.  Cats purr when they feel affectionate.  Squirrels'
clucking/chirping expressions usually sound rather nervous, but maybe
they could be interpreted as a "blown" kiss.

Good luck!

I once had a cat who hunted squirrels
- he lost half his face once, but like most big game hunters he persisted

If you want schmaltz, then try the squirrel raising the kittens in the
tree, while the mother is fighting off rats

You could introduce a sub plot where the squirrel (tree rat) explains
rat kung fu to the cat.

Personally I would not go there - it stinks of sibling rivalry

Well, I had a little idea what it could be, so here it comes:

There was a blue cat beneath a tree. She was a real beauty queen. From
up a tree, a black squirrel this did see. She's so lovely, thought the
squirrel, how could she be with me? I will ask her to come, climb up
to tree, then she will be with me. Then the squirrel went and said to
the cat, will you come and climb up a tree? As high as that you far
can see. The cat looked up and said, I'd like to come but I don't how
far can I be. The squirrel aswered, on time you'll be back, I'll
promise that. Then agreed upon that, and climbed up a tree, black
squirrel and the cat.

I don't speak english as my native tongue either, so there might be
some errors with grammar that I don't see. But if you translate it
then it doesn't matter really.

I translated it with bablefish but I don't know how accurately it translated.

Il y avait un chat bleu sous un arbre. Elle était une vraie reine de
beauté. De vers le haut d'un arbre, un écureuil noir que ceci a vu.
Elle si belle, la pensée l'écureuil, comment pourrait-elle elle
est-elle être avec moi ? Je lui demanderai de venir, s'élever jusqu'à
l'arbre, puis elle sera avec moi. Alors l'écureuil êtes-vous allé et
avez-vous dit au chat, venez-vous et élever levez-vous un arbre ?
Aussi haut que ce vous loin pouvez voir. Le chat recherché et dit, je
voudrais venir mais je pas à quelle distance peut I être. L'écureuil
aswered, à l'heure où vous serez de retour, je promettrai cela. Ce
alors convenu, et élevé vers le haut d'un arbre, d'un écureuil noir et
du chat.

myoarin: Thanks for the ideas. I really like the intertwine tails idea :)

quantummechanique: Nice one :) I will try to translate it to french
correctly & post it here (the babelfish translation don't have much
sense).
