I thought the same Sam, hope he likes the newbie. However Dave said if it didn't work out, he'd take the cat back after his holiday, it sounds like it really bonded with his daughter, sitting with her while she was colouring in on the doorstep
and them falling asleep together
I know that she will be gutted, but it's the right thing to do for now and hope it all works out.
One way or another, a cat WILL be getting a new home with Dave and family later in the year, he's seen how serious his daughter is about having one and how much she loved it so he's finally relented (Yay!)
