By getting your cat fixed after her first litter, you will prevent future unplanned litters and contribute to reducing the overpopulation of cats. Having your cat spayed will also reduce the risk of certain health issues, such as mammary tumors and uterine infections, and will help your cat live a longer, healthier life.
It's important to keep in mind that if you plan on having your cat fixed after the first litter, it's crucial to keep her separated from unneutered male cats during and after the nursing period to avoid unwanted pregnancies.
Before making any decision about spaying your cat, it's always recommended to consult with your veterinarian. They can assess your cat's specific health and provide the best advice on the timing and procedure for spaying.
