So we took in a stray about 4 weeks ago. She had been coming by for a couple weeks before we decided to take her in. Dont worry we went to the humane Society and she is not chipped, we also asked all our neighbors and no one claimed her. About 2 weeks ago I noticed she was getting pretty wide and that her nipples had gotten quite large. As I came to find out these are both symptoms of pregnancy. Fast forward to today I notice some crusties near her nipples and tried to express milk and a yellowish clear liquid came out, colostrum is my guess. Her behavior today is odd as well, she is still eating her normal amount just a lot slower and she keeps sitting down and then bolting up like something has scared her. This is odd for her cause the past week she has literally slept most of the day and when she moves its pretty slow. The strangest thing though is that she keeps scooting her butt across the rug, I have never seen her do this before. Should I be keeping a closer eye on her? Do you think these could be weird signs of labor? I have no idea when she became pregnant so I have no idea how far along she is. I really appreciate any and all comments or suggestions, I have never had a pregnant cat. O and I think I should mention we are getting her fixed ASAP and all the kittens will be fixed before they go to their new homes.
