Hi Emz77.
Kittens shouldnt be flea'd so early probs better to leave her upto 10/12 weeks. If she is really bad you can bath her, with cat shampoo its medicated so shouldnt harm your new kitty cat, but wear thick clothing and gloves as she is ferrel and may scratch you, ask someone to help you. Or use an electric flea comb.
Cats should only be neutered at 6months any vet will tell you that. Make sure she has plenty of toys. Cats are different from dogs so dont stop her from trying to bite or claw you, they need to learn to use these skills when outside the home, you can just tap her nose gently and her paw when she hurts you, but not so you hurt her, cat scratches never scar, this will teach her to withdraw her teeth and claws when playing with you, but will enable her to know the difference between inside the house and out. She will need a soft cuddly blanket or bed to snuggle, let her snuggle you. A cat will only trust you when she wants to, they usually choose there owners not you choosing them lol. So you will need to handle her alot. You will have many funny playfull years with her. And even though her mother was weaning them off her, she may still need some milk at such a young age, you can buy kitten milk, dont give her human milk its made differently.
Ooh good luck. I just love cats.
Hope this helps.
