During the estrus period, the female cat can prepare some toys to distract the cat, or sterilize the cat. Of course, the owner should consider whether to let the cat mate. If you don’t want the cat to give birth to kittens, it is best to take the cat as soon as possible. Pet hospitals perform spaying and neutering surgeries to relieve cats' pain. In addition, you must go to a regular pet hospital when undergoing sterilization surgery to avoid life-threatening injuries.
