How to calm a cat in heat
Recognize that your cat is in heat.
Make sure that the behavior your cat is expressing actually means that she's in heat and not sick. An unspayed cat in heat will vocalize a lot, be restless, rub against people and objects, and roll around on the floor.
If you stroke her lower back, she'll respond by raising her pelvis and shifting her tail to one side. The normal breeding season for cats is between spring and late summer.
