Also known as “calling,” your cat may wail, moan or meow more than usual while she is in heat. Her cries may sound distressed – and may even keep you up at night.
How long does a cat stay in heat?
Each heat generally lasts several days with the average length being six days. If the queen (an unspayed female cat) is not mated during estrus, she will go out of heat for a short period of time.
Do female cats suffer when in heat?
No one can say with any accuracy that heat cycles are painful to cats; however from the calling (loud yowling) and other symptoms they exhibit, it would appear that they are very uncomfortable. A kitten can have her first heat as early as 4 1/2 months, so don’t fall for that old “wait until six months to spay” advice.
