My much loved, MASSIVE middle cat of 3, Biscuit, is 10 months old. We got him at 5 weeks because his mother was ill. He was initially anxious whenever I left the room, but bonded really well with my slightly older kitten.
Biscuit was neutered at 12 weeks. He's a little bit vicious and combined with his fussiness, the vet thought he was just anxious. He is now on a supplement for his anxiety and is slightly less fussy, but basically, Biscuit is still very bitey and scratchy.
I'm an experienced cat-servant. I adore the little fecker. But we're a little scared of him. He sometimes just approaches me for a little swipe, or gives me a non-affectionate chomp.
He'd benefit from a run, I think, but he's too scared to go outside.
(We have no small children in the house, btw.)

Any help at all would be massively appreciated (also asking Litter Tray, but the traffic here entices me).
