I ahve a few ^^
Keep it's litter box in a secluded, quiet area. A cat does enjot it's privacy.
Keep it's little box clean and tidy. A cat will nOT use a dirty, smelly litter box because the smell will become too powerful for it's delicate nose.
Give it a small variety of foods. I say small because if you give it too broad a category it may start rejecting everything you feed it, in search of the perfect food.
Always provide fresh water with some watered down milk (Or pure milk seeing how young it is) Put out both because the chemicals in regular water may drive the cat away in search of some yucky muddy puddle to drink from x_x
If your cat starts to claw at furniture, growl like Mama cat. It may seem ridiculous, but why do you think Mother cat growl at their kitttens?
I suggest NOT declawing a cat. it is almost like taking away your fingers, and they will be incapable of grooming themselves.
If you have any questions feel free to PM me ^^
