Quiet! I can't take it anymore!  

While she is in heat she won't stop yowling. It's actually really uncomfortable for unfixed pets to be in heat and not have...any umm...lovin' going on! lol

So it's great that you are planning on getting her fixed-the sooner, the better for her!

You should make sure she can't get out because chances are she'd come back pregnant. I don't think you want a pregnant cat. I remember when our cats whent into heat.... didn't bother me so much probably because of all the other noises.

It seems like cats go into heat at the most inopportune times. Is there a room away from your sleeping area that you can lock her in for the night? Also you might call the vet and see if there is anything you can give her to relieve the yowling (short of the spaying). Also check your local humane societies and see if they offer assistance in spaying. I know in my area there are several agencies that offer coupons for money off on spaying and neutering.

At this point in time you need to be really really careful that she doesn't get out. It's amazing how sneaky a cat can be, and how fast they can get out. When they do get out they aren't too choosy about who they are amorous with, but the end result is always the same, kittens! Until the heat passes (I think it is about two weeks) she is going to be very vocal and very uncomfortable.

When I had my kitten for the first time, I too faced this problem. It will not stay at home and pesters us to leave it outside. In fact it did not come home for 13 hours. Then we got it spayed. Even then, the intensity got reduced but once the kitten stayed outside for 3 1/2 days and we all got worried. Like a mad woman, I was wandering in the streets and searching for the cat. Do not know what it ate for 3 days. Then as usual, one day early morning it came back. Get it spayed soon. Intensity will get reduced.

That was really annoying I don't think there is any solution than that rather than strap her mouth. Can you tranquilize him or feed him some food that may loose his consiousnes and then you can go to sleep.

I would be inclined to get her spayed as soon as possible hun. Once she has been fixed, the yowling will stop and you will get some peace and quiet again.
