I was only gone the day but took my suitcase which she's been frantically clawing at and doing cat screams and refusing to eat since I got back.
I assume something frightened her whilst I was out but obviously as she's a cat she can't tell me.
The wailing banshee is now parked on the closed toilet seat in the bathroom (I had quite a struggle earlier to get her to cease and desist - I just wanted to use the loo but she refused to vacate her spot).
Just leave her to calm down? She's not normally like this and I don't think it's anything physical
