Sorry - long.
Dc1 - original cat, is 8. I hand reared her from 2 weeks, (semi feral farm cat had kittens, this one couldnt suckle properly). She can be fiesta but is a scardey cat with other cats, will always run away rather than attack.
Dc2 - in November, a starving kitten (4 months ish) turned up, slept in the shed fir a few days and refused to leave, really nasty wound on her back. Failed to find an owner, not chipped. So, she moved in.
All was well to start. Dc2 was feeling ill so didn't move much, dc1 studiously ignored her presence.
Once dc2 was better, the stand offs started, a few scraps, dc1 couldn't stand dc2 being in season and actively sought her out to have a go.
They had settled down a lot - dc1 decided to live upstairs, coming down to go out. I moved her food upstairs.
Dc2 stayed downstairs. Would sit at the bottom of the stairs in the morning waiting for me.
However, dc2 has started coming upstairs. She likes to sleep on my bed (previously dc1 had done this, or at least in my bedroom). We've had a couple of weeks if them both sleeping in my room, but now dc1 has not been home over night for several nights. I dont think she's sleeping outside.,
I feel awful fir her, that she feels she can't come home to sleep. She wasn't in all night last night (I was up several times to check) but appeared on the shed roof at about 8am (which makes me think she hadn't slept out) . She came in a dc2 chased her up the stairs.
Dc2 is a lovely little cat to people, very affectionate, the children love her (they have to be careful with dc1 when stroking etc as she has a nipping habit)
Any advice? When they were in the scrapping stage, I left dc2 in the front room/hall with a litter tray . Dc1 doesn't use a tray so had rhe rest of the house in so she could get out.
I feel dc2 is too big/active for this now, abd wouldn't be able to get out.
