Overview
If your female cat is in heat, you might notice she’s more vocal, restless, or keen to get outside. It can be a little worrying if you’re not expecting it, but it’s what she naturally does while looking for a mate. The best thing you can do is keep her safely indoors — away from male cats — to avoid any surprise litters. Other ways of helping include:
Creating a calm, safe space at home
Giving her extra attention and gentle fuss
Keep her busy with playtime or treat-filled toys
Try a pheromone diffuser to help her feel more settled
Double-check that windows, doors, and cat flaps are secure
Most female cats (known as queens) have their first heat when they’re around four to six months old — and they can get pregnant even on their first cycle. If they don’t mate, they’ll usually come back into heat every couple of weeks throughout their breeding season (spring and summer). You might spot signs like loud calling, rolling around, restlessness, or trying to sneak outside to find a mate. The simplest and safest way to avoid heat cycles and unexpected litters is to have your cat spayed.
