Is it not strange that when a man physically impregnates a woman, he does so with what looks like a brood of serpents?
Sperm, under a microscope, looks like snakes. Each of us began our time on earth as one of these.
Eve was deceived
by a serpent in the garden, and became pregnant, giving birth to the seed of the wicked one, named Cain, who slew his brother Abel.
Jesus was not conceived by one of these. His mother was pure, a virgin.
Luke 1:34-35 KJV | Then said Mary unto the angel, How shall this be, seeing I know not a man? And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.
Feminine Products for Pets
Why is there no market for this, for animals?

Is it only for humans? There seems to be no demand for feminine care products for animals.
Do animals have menstrual cycles, like women? Do you ever see blood on their fur or blood dripping out? I have never seen any sign of menstrual cycles in animals.
Genesis 3:16 | Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children...
The overwhelming majority of mammals do not menstruate. Instead, they have an estrous cycle where the body completely reabsorbs the old uterine lining if pregnancy doesn't happen. True menstruation—spilling blood and tissue externally—is mostly unique to humans, if it could be said that any of the others even have the same.

For example, the menstrual blood discharge of the Eastern gorilla, a primate, is not visible to the naked eye. This primate is usually larger than a human, so the argument cannot be made that it is because it is a smaller animal that the blood cannot be observed. The menstrual blood of this gorilla, if even any, is not seen.
Human women are in a special category of life. They have an issue of blood, and they see it!
