Female cats can't recover their fertility after sterilization. Sterilization is the process of preventing cats from getting pregnant by removing their fallopian tubes and uterus. This means that the female cat can no longer be pregnant or have offspring. The effect of sterilization on female cats is permanent and irreversible. Sterilization helps to control cat reproduction, reduce the number of stray cats, and prevent some health problems related to fertility, such as uterine infection and breast tumors.
