My cat is a complete nightmare.
She has both the kids scared to death of her, has the dog terrified and even attacks the wife on the odd occasion. she sleeps most of the day and goes out at night on her own free will.
yes we let her up the stairs but keep the kids doors closed but leave ours open as she will sleep under our bed. most of the time you'll find her on the top landing sleeping and the only time you see her is when she wants food.
were trying to get her into the habit of being in at night and out during the day as its coming into the colder nights but she goes daft behind the door at night to get out..
Im not a cat person wasn't even me that wanted the cat but don't think any of us would rehome her or try and get rid of her.
she has her nice moments but 9 out of 10 times shes out for blood for no reason...
