3-4 wks sounds about right based on the degree of mobility. I'd be
supplementing with formula with a bottle or at least in a bowl if she'll lap
it up.

I'd also consider 'rescuing' another one. I've read that single kittens have
a tendency to become biters because they don't learn the limits by playing
with their siblings. If this kitten isn't getting around too well yet then
she hasn't engaged in much kitten play with her littermates yet.

Under normal conditions I'd say take the kitten back to spend more time with
it's mom but the owner doesn't seem very responsible if he/she is trying to
get rid of the kittens this young and permits the children to behave this
way.

It's probably a tabby but it's hard to tell without seeing the cat.

Good Lord in heaven. I hope the parents of the little girls rot in hell.
Your kitten is *way* too young to be away from its mother. But she's a far
sight better off with you than she was living with the children of idiot
parents. If you know them, see what you can do to convince them to spay the
mother cat.
That said, I think your kitty will be fine eating wet (kitten) food. You can
supplement her diet with KMR (Kitten Replacement Milk)...or another brand. It's
available at the vet's, and I believe Wal Mart even carries it.
Sounds like your kitty is  a tabby striped moggie. The best kind of cat. Enjoy
her.

Does the kitten have teeth?  They come in generally 3-4 weeks of age.  And
also are a bit "off" on mobility.  Is kitten trying to "suckle" the cat
food?  Or is he eating and chewing?  You can mix kitten formula in w/the
food, but a long as he's eating canned well, not necessary.

You should also make vet appointment in the next two weeks - the vet will be
able to determine age a bit better, as well as start vaccinations and
worming.  Take a stool sample w/you so they can test for specific worms.

What a kind soul you are for rescuing the kitten.  Hopefully the other will
also find a good home before the little girls drown them.  Somebody should
also get the mother cat and get it fixed - then no more unwanted babies.
Those people should not be permitted to own a pet - they're own
irresponsibility by not getting the mother cat spayed resulted in an
unwanted litter.  She'll soon go into heat again, and the cycle continues.

As a foster for two shelters I am torn - I look forward to kitten season
because they are so damned cute, but at the same time I get extremely ticked
off because people aren't responsible enough to get their pet fixed.  God I
hope the parents of those little girls are doing a better job raising their
kids!  Perhaps the parents should be fixed too.....(I'm assuming they are
bad people due to lack of cat care, I know I shouldn't assume).

Julia-
 I can't answer your other questions, but I think I know what type he is.
Based on what you said, it could either be a tabby as you said, or a bengal.
Believe me, I have 4 cats that look just like that, and one of them is named
Tiger.
