A stray cat adopted me when i moved to a new house. About two months ago, I noticed she was pregnant. She has shown signs of nesting for the past 3 weeks now, today she has been very vocal, but she is not following me around like usual. Just whenever I am in the same room with her she talks a lot. When I pet her belly it feels hard, usually I can feel a kitten kick or move around. Could she be going into labor? She is acting very nervous, and her eyes look scared. What do you think?
