Comfortis dosage

How much Comfortis would a 1 lb. kitten take? I have some crumbled pieces of one of those huge tables and I want to mix it with water in a syringe?  And way to get the right dose for them?  One is about 1 lbs. 5 oz. but they're all 3 around the 1 lb. mark.  I saw a flea on one of them.

Thank you!

Why are you using Comfortis on a kitten? Especially one that small...

I do not think it has been prescribed or recommended for kittens.

That is a big concern...their bodies cannot adjust to this stuff...

Kittens are also hyper. they have to be. They are babies and toddlers...

I saw a flea on one of them. So what is safe to use? They are 7 weeks old.  I don't want the fleas to get out of hand.  Another one of my fosters had gone to PetSmart yesterday for adoptions and I think she brought a few fleas home.

oh----sorry, I may have mixed that up with another medication... 

I do not know about fleas..Artie has never had any..
