Maybe a huge truck went by or a car backfired. That's how my girls act when something scares them (well, not quite to that extreme). She could have even seen another cat or a dog outside and it freaked her out. Poor little girl.

 

I agree sounds like SOMETHING freaked her out. I would do a walk through your home to be sure nothing got in. Check windows and doors for spray marks (or footprints if you have soft soil.. ours is frozen) ect. ect.

you COULD prod her for painful areas... but sounds more scared then hurting to me..

 

No animals can get into our house. Back yard is fenced in (6ft plastic privacy fence). The only thing that drove past our house was a cleaning truck from the city, but they come through once a week ad she never acted like that before (only on new years eve with the fire works going off).
We hardly have cats going past our front of the house. I put her in her litter box to pee, cause I had the feeling she never went all day because of her behavior. She is almost back to normal now. I am puzzled

 

Maybe she read your diary....

 

maybe she watched "Twilight" while you were out. I would react badly if someone made me suffer through that too... and not let me sleep through it.

 

@marie73: no diary here Never had one

@BotanyBlack, she was watching TV, before I left with my son. I think it was a cartoon on it.
