I got my first kitten 3 years ago.
I decided I wanted a female as they are supposedly slightly smaller and less likely to roam/fight. I picked what I was told was a female only to take it to the vets and discover it was a boy! He is massive now but has been neutered and doesn't fight or wander off and I wouldn't swap him for the world.
I also wanted the cute black kitten from the litter but this was the liveliest and I was advised to get a quieter one as it was my first time. Mine was like a tasmanian devil once he'd settled in, not quiet at all!!
He ripped the wallpaper to shreds in the kitchen, he used to climb up the wall with one paw each side of the corner, I swear there were claw marks about 2cm from the ceiling!
Make sure he/she has a scratching post to scratch and hopefully they should leave your wallpaper alone (mine doesn't so i haven't got any now, its all paint!)
It will probably climb your curtains, get into any hole/space it can find (behind/inside the washing machine, on top of shelves, behind the TV etc) so make sure wires etc are out of reach and check the washing machine before you close the door!
Get it neutered / spayed as soon as your kitty is old enough, usually about 6 months, and make sure it is vaccinated before going outside.
You will need some toys to keep it entertained, a bed, litter tray, scratch post and a cat carrier for taking it to the vets.
They are sooo cute and playful when they are this age, good luck!
