aww shes georgous and yes people say naughty tortie i think its mainly because torties are girls and girls are usually bossier than boys and kittens dont need kitten milk (marketing ploy) just plain fresh water
They don't actually need kitten milk, it's a marketing ploy like issey says, but some of them like it. My 13 year old cat still does I get it for him occasionally if he's off his food for any reason. I bought it for him originally because when we adopted him he was a tiny, foundling rescue kitten who wasn't old enough to have left his mum, and I thought he might enjoy some milk. He loved it.
She had a few fleas on her (came from a house full of cats) hence why took her to see the vet nurse, they sprayed her with frontline but she is still scratching every few mins anything else I should be doing?
A little wee is excellent - even though small, it means she knows where her tray is and how to use it. That's a biggie with a new kitten/cat.
I'd let her stay by herself if you want although she might like some company as it will be the first night in her life that she's been on her own. (Bet you wouldn't sleep yourself and would be in there every 10 minutes to check on her.) I always have my boys sleeping with me so the question doesn't arise for me - other posters might give you a clearer steer.
