It is very uncomfortable for cats to have sex because cats secrete sex hormones when they are in estrus. If they do not mate, it will cause anxiety and other symptoms in cats. In severe cases, it can even lead to pyometra. During the cat's estrus period, you can let the cat play with more toys to distract it. If you don't want the cat to have children, it is best to take it to a pet hospital for sterilization surgery. This can reduce the cat's pain and avoid the occurrence of diseases.
