I have a cat under the age of one who is expecting. I believe the day she got pregnant was March 3, when she escaped the house for just a little under an hour. Now her stomach is big and hard she is also having a little bit of discharge from her vagina, constantly cleaning herself and being very affectionate towards me and the dogs. Her nipples are pink and enlarged. Despite all this she still runs around climbs up her cat tree and acts "normal". Help.
