My cats acting really odd?

She hasn't got fleas, no new carpet stuff I've used, just hoovering as norm. Nothing has changed. Gonna take her to vets, then cat psychologist!!! I have been told about static that cats can pick up but don't feel that's it, I know her and she has never acted like this through all these years.Thanks to all. x Sorry if I've done this wrong, can't find the add for the original question, it's just not there for me!
