Are they scared of something outside, do you think? Or is this normal cat behaviour? They're shut in the kitchen area (which is big), with a catflap into the garden at night, while the dog (who they're none-too-fond-of) sleeps in the family room.
Everyone else has gone to bed, I'm MNing with them in the kitchen. The cats are just sat with me, and it's like they're on edge. One is just staring at the catflap. As far as I know, nothing else comes in at night (but I can't be sure I suppose). There is a fox that comes into our garden occasionally, we've seen him.
I don't want them to be feeling unsafe at night
