It is a normal physiological phenomenon for female cats to turn blue in estrus, which usually occurs once every 2-3 weeks. In estrus, the female cat will become very irritable and increase her reproductive behavior, which may bring some inconvenience to her owner. Here are some ways to relieve the mother cat's depression:

1. Let the female cat exercise more.

Providing the mother cat with enough exercise can help her consume a lot of energy and relieve her tension and estrus symptoms.

2. Provide the mother cat with enough food and water.

In estrus, female cats will lose their appetite because of nervousness, so it is very important to provide them with enough food and water.

3. Control indoor light

The intensity of indoor light will affect the physiological cycle and estrus of female cats. Therefore, the intensity of indoor light can be properly adjusted during estrus to help the female cat relax and relieve symptoms.

4. Use drugs to control estrus of female cats

In strong cases, drugs can be considered to help the female cat control estrus. Some drugs can temporarily prevent female cats from estrus, but they need to be used under the guidance of veterinarians.

In short, compared with isolating the female cat, it is better to use the above methods to alleviate the estrus of the female cat and keep the female cat healthy and comfortable.
