Female cats do not menstruate and only go into heat during their menstrual period. Generally, female cats will have their first heat when they are 6 to 8 months old. If a female cat is not able to mate after she is in estrus, the eggs will not be stimulated to be released. Unfertilized eggs will be absorbed by her own white blood cells and will not be expelled from the female cat's body. If a female cat bleeds when she is in heat, it means she is suffering from a gynecological disease.

Solutions for cats in heat

1. Close the doors and windows at home to prevent cats from attracting other cats to come when they are in heat.

2. It is recommended that cats in heat be locked in a cage to prevent the cat from escaping and causing other accidents.

3. Secondly, the owner can put the female cat in menstrual pants to prevent accidents.
