Fetchin him bak again

Hi
We now have a happy home all cats and the 2 kittens getting on great.
Then i get a message that one our kittens we sold(sold purely so they wouldnt get used as bait cats etc you hear horrible storys) is being sold again!.
This poor kitten has had 3 homes and he only 12 weeks old.
It started when i sold him to what i thought was a nice girl for £15. Then i spotted a add on facebook her sellin him for £25. I commented on the post sayin please who eber gets him to contact me to make sure he safe.(after going down through the first owner) the new owner did get in contact and was really happy with him.
Yesterday i saw him addvistised AGAIN and again i sent a message asking why? She just split with her partner and is going to be homeless so i bought the little fella back.

He is in good body condition etc and has had his jabs but he a wreak and i dont blame him.
Hissing and swiping at everything and everyone. He was such a charter before he left here. I know he gone though hell being moved about but he going no where now but how do i get him to come round.
his brothers try to play with him but he just hisses. He now hiding under the bed and i am in 2 minds weather to let he come out on his own. Or get him out.
please sny advice would be great .
Thank you

Aw, poor thing. I'd give him some space. Is there a room you can put him in where he can acclimate back in at his own pace? So glad you took him back.

Poor boy's been through a lot! I'm glad he's back with you.
I would treat him as any new cat in the house : keep him in his own room until he settles back in, then re-introduce him slowly. It may take him awhile to calm down, but as long as you go at his pace, he should re-adjust.

If you need, we have some great articles on introducing cats :http://www.thecatsite.com/a/introducing-cats-to-cats

He meantal.lol. My ghost (1 of the kittens we kept 15weeks old) kept wanting him to play so he kept running under bed so i couldnt get him to put him another room to settle.
When he did lash out at u it wasnt really to bad he actually didnt use all of his claws just the tips. And would just mouth your hand if u kept ur hand there.

Now after ghost not giving up to get him to play he is chaseing ghost around and doing the ferret dance to get ghost to play.
What a change. Still eatin like a horse although he not searchin for it all over.
His mum seems to recoise him anf he gets his baths etc.

Loves to watch birds out of the window. Or sleep on our scratching post. But he now started to snuggle and want to be with us. The rest have accepted him striaght away. We must have the most laid bak clan of cats ever.lol.
