Help! Please

I am cat sitting for a friend. She has a male and a female. The female is in heat and I am afraid the male might get her. I have them in different rooms but the female keeps getting out. The male is 6 months old can he get her pregnant? He seems to not want anything to do with her but I don't know if my friend really wants a litter. do you think he can get her pregnant yet? I'm not sure why she doesn't have the darn guys fixed yet?

DeDe's Mommy,

Yes he can get her pregnant and yes you need to keep them separated. The heat should only last about a week. But nonetheless, keep them apart. I think you would be doing both cats and their owners a favor. If your friends want them to have a litter, they can always mate them the next time the female goes into heat.
