If you have an unspayed female cat, you'll know when she's in heat. But how often does this happen?

The Seasonally Polyestrous Cycle

Cats are "seasonally polyestrous." This means they can go into heat multiple times during their breeding season. In the Northern Hemisphere, this season typically lasts from February to October, triggered by longer daylight hours.

Frequency and Duration

A cat will go into heat (estrus) typically every 2 to 3 weeks. Each heat cycle usually lasts about 4 to 7 days. If she doesn't mate, she will go out of heat for a short period and then go right back in.

Conclusion

The only permanent way to stop the heat cycle (and the noise!) is to have your cat spayed. This also prevents unwanted kittens and reduces cancer risks.
