I have a cat that is obviously pregnant, yet she still wants to mate and the males still chase her down. Is this possible? Dolores

If a cat is pregnant, she will not continue to attract toms much less be interested in mating. The gestation of a cat is about 2 months and most cats don't "show" like you think they would. The first sign would be swollen mammary glands and prominate nipples. How old is the cat and is the cat normally overweight? Did the onset of the "pregnant look" come on quickly?
