I believe my 5 year old cat is pregnant. She is an indoor cat who accidentally escaped on 6/2/15 and 6/9/15. Since that time, she has not shown any heat signs, her stomach has become quite large and hard. I know that if she is pregnant, she would be about 61 days from the second time she got outside. However, at this point, I have not been able to feel or see any kitten movement and I am not quite sure about her nipples. While her nipples are more "noticeable", they do not appear to be enlarged although I am not really sure what her non-pregnant nipples looked like. I guess my questions is, do you always see and/or feel kitten movement and is there always a marked difference in the nipples. Any assistance would be appreciated. Thank you all.
