My cat aura is a first time mom. Not sure exactly how far along her pregnancy is but she is noticeably round and there is dry white flakes on her pinky enlarged nipples. She seems very agitated. Will be laying in one spot but then moves to another spot and so on. Is this normal? Also when do they start looking for place to give birth? I have pulled out a shelf from my chest of drawers and put clean towels in for her but she doesn't seem interested in it. She is sleeping a lot but still eating fine. How do I know ( through behaviour and physical signs) that she is preparing for birth? I am a first time Granny aswell so any advice will help lol.
