What to do when your female cat is in heat?

There isn't a great deal you can do, except provide comfort, and to ensure she is eating. Being in heat is a stressful time, so some cats do not eat for the duration. Make sure there is no way for her to escape outside, and is ideal to get her spayed after her heat has finished.

A cat in heat will become much more affectionate with everything she comes across, she will howl an call day and night and will attempt to escape outside at every opportunity she sees in order to find a mate. She will often present her rear end and keep the front half of her body close to the ground, and tread with her back feet. Females cats in heat will also spray vertical surfaces in the house in order to attract a mate.
