Last Sunday I took a pregnant stray in during a storm. She has taken shelter in my basement and became very friendly with me before having her kittens on Thursday (yesterday). There have been a few times that I’ve walked down to check on her and she is huffing and breathing heavily and has a slight jerking motion in her head. When I sit beside her and pet her she then begins purring and kneading. Is it normal for a new momma to react this way when nervous? She does not hiss or growl. I have also noticed that she is constantly pawing at the kittens, is this normal? She is eating and drinking. All kittens seem alert and are nursing.
