I've been feeding a stray cat for a couple months. She ate up to 3 to 4 cans a night. After awhile She looked heavy in the back end then she seemed thinner (we figured she may have given birth). But really not sure she was pregnant she wouldn't let us near her. Two weeks ago she came closer and eventually let me touch her. I noticed her nipples seemed to have the hair pushed away and they were sticking out, she seemed to hang out on our porch for long periods of time after eating. We thought if she had kittens would she leave them for so many hours, it appeared she stayed under our porch overnight as well, So I then thought she was pregnant so I was able to grab her with a towel and bring her indoors 2 nights ago, although she was frightened at first she calmed down and seemed to like the warm room. She isn't afraid of us at all she is happy and content, however now her breasts are warm and very swollen & hard. I plan on taking her to the vet but I am sick with concern she has kittens out there somewhere! Only thing is how calm happy and relaxed she is, my thought is if there were kittens she would try to get out of the bedroom. Ugh I just wanted to help her and I talked with a woman from the shelter she said if she were nursing her nipples would look used and they don't . Any thoughts?
