A miracle cat that eventually undergoes neutralization surgery

There are different opinions about the neutralization of pets, but there are probably many people who think positively about neutralization of cats. He also recommends surgery for cats because neutralization is very simple and recovery after surgery is also fast. In addition, since cats that have not been neutralized cause various problems due to estrus stress, I think that neutralization is also a desirable route for the health and various aspects of the cat.
