UPDATE: Teddy is a much loved member of the family already, he seems very happy around the girls and has already figured out if they are annoying him to take off up the stairs as the girls can't get past the gate.
DD1 likes picking him up and he seems ok with that but we are teaching her how to do it so she doesn't hurt him.
We bought him a scratching post with a little ball attached and as he gets older i will make him a scratching/climbing post.

Going to fill up a water bottle to spray him near my curtains but in the meantime he's running around the house during the day, hiding on the stairs then sleeping in the bathroom at night.
He's NOT a fan of the dogs so need to work out a way to introduce him to them.. any tips?
