I have raised a precious cat. I want to have offspring, and many relatives and friends want to do so. However, I am always not in heat, nor pregnant, and I have a headache~~~ There may be five reasons below!

1. Long-term, simple feeding of too much protein, fat and carbohydrates, coupled with lack of exercise, makes female cats too obese, with fat deposition in the ovaries and fatty degeneration of follicular epithelium. The affected animals show no estrus, or even though they are in estrus, they are not in estrus. Conception, or pregnancy but early miscarriage.

2. Malnutrition. Common rations include monotonous, poor quality or lack of essential amino acids. Minerals and vitamins etc. Vitamin A deficiency can cause endometrial epithelial cells, egg cells and follicle epithelial cell degeneration, follicular atresia or cyst formation; vitamin E deficiency can cause pregnancy interruption, stillbirth or hidden abortion (fetal absorption); vitamin B deficiency, It can weaken the contraction function of the uterus, destroy the production and ovulation of egg cells, and prevent the female animal from being in estrus for a long time. Vitamin D deficiency can cause metabolic disorders of minerals (especially calcium and phosphorus) in the body, which can indirectly cause infertility. In addition, deficiencies in calcium, phosphorus, selenium, cobalt, zinc, etc. can also lead to infertility in female cats.

3. Abnormal development of sexual organs, such as underdevelopment of reproductive organs or lack of reproductive ability (infant disease) when reaching breeding age; hermaphroditism, that is, having both male and female gonads, or having one kind of gonad, but other reproductive organs look like another Gender; abnormalities of the reproductive tract, such as slender cervix and uterine horns, defects or atresia of the cervix, too narrow or atretic vulva or vulva (unable to mate), etc.
