I have noticed the last couple of days she starts shivering occasionally, she is awake at the time but seems relaxed. She is eating and drinking normally, no problems with litter tray and an indoor cat so no trauma or eating anything I don't know about. I am at home packing at the moment most of the day so I would know if she had a bad fall indoors. Her temperature seems normal (have felt her ears) and she is alert and clear eyed.
The house is a sea of boxes ready to move, with lots of empty shelves etc. - I think she may be stressed due to change in her environment. She has also become clingier during the same time, actually trying to sit on me whereas she normally just likes to hang out in the room keeping us company.
However is there another possible cause I need to consider?
Thanks!
