I used to have a female cat that was in heat and she was playing with me, and my sister said your cat is in heat so try not to be very rough with her. The others can sense that she is in heat and she wants to go outside with the males that are outside and to mate with her.
So my mom told me to take her to mine sisters room and leave her there so she would not be mated and not having any kittens this time so be very careful about what are you're trying to do.
