new kitten found

we found a kitten tonight and she is ate up with fleas i have some advantge II for cats 9 pounds can i put a small amount on her she looks to about 9 weeks

When I had some flea ridden kittens I had many people tell me to bathe them in Dawn dish soap.  While the kittens did not appreciate it, it did work.  I would not use that on your kitten- she is far too little for it at 9 weeks.
 

Research this flea med before putting anything on them.  Many flea applications are TOXIC to cats/dogs. 

I do not know if this product is one of them.

Hissy rescued some kittens earlier that still have neurological damage from flea treatment.
 

Search these forums for 'fleas' and you will see some safe alternatives for kittens recommended.  Sorry, I do not recall the product.  I've never dealt with fleas and the product name escapes me at the moment.

Here's a recent topic regarding fleas:
