urgent plz help me out!

i have ha silver grey persian cat(female). she is about 1.5 years. she is completely indoor so we tried to mate her with our friends cat but he said after 2 days that she is not responding may be she is not on heat. so we take her home . but now after about 9 days she is acting like she is prego. her sound is loud and terrifying . she is barely taking feed and feel soothing when i pat her stomach. also she is getting lazy and affectionate. i dont know if she is on heat or having a belly pain or may be pregnant... what should i do

I would say she is in heat now, that is what it sounds like. They raise their rear end up high to be scratched, and almost have non-stop meowing. You may want to look on the older threads for more clues. Are you sure you want her to have kittens, there is always a risk you know, and there are SO many unwanted ones now. Good luck in what you decide!
