hi i was just wondering if anyone could help . my cat ruby is 1year , house cat due to living on a busy road . she got out about 3-4 weeks ago was missing for 3days. not sure if she was in season at the time but was acting very strange . i have noticed her nipples are getting bigger ? i have never had a pregnant cat so any advice would be great. please no judging me i took her n her sister on at 6months as they was un wanted , and didnt think she would sneak out :/ . x
