Back from holiday today and the cat is AWOL. Been back about 5 hours with no sign of her. She has form for this.
We went away a few years ago and my Mum came in to feed her. Cat disappeared for several days which led to my mum losing a lot of sleep and planning how she was going to tell us she'd lost the cat (DM is a worrier).
To avoid the trauma to DM we asked a friend to feed her next time we went away and friend didn't see the cat for the whole 10 days, but had to assume all was ok-ish as some cat was coming in to eat the food. I really didn't enjoy the holiday as friend was honest about the cat situation (even though she took to spending hours at our house to try and spot the cat) and 10 days of no sightings was enough to remind me I am my mother's daughter. When we got back it was about 4 hours before the cat returned.
I pushed that next time we spent money on a cattery so i'd at least know where she was but cattery owner was honest on pick up that she hadn't settled and had seemed quite scared the whole time. Cat shouted at us constantly for 48 hours when we finally got her home.
So this holiday we asked a friend's daughter to stay for the week, thinking that would be nicer for the cat to be at home, but with company. She apparently did stay around and friend's daughter took some nice photos of her but now we're back.... crickets.
This is a cat who spends all day and half the night on my pillow when we're all at home.
So,
You are being unreasonable = you should be worried, you heartless human monster.
You are not being unreasonable = she's punishing you and she knows exactly what she's doing. Hold your ground.
