In female cats that have not undergone ovariectomy, uterine infection is the most common reproductive disease and is likely to be life-threatening if left untreated. In female cats in the breeding season, almost all feline viruses may cause abortion. Compared to dogs and humans, cats are less likely to suffer from reproductive tract cancers. Uterine infection (uterine pus) usually occurs within 4 weeks of estrus and is most likely to occur after ovulation, but unmated cats may also contract the disease. Early signs of uterine infection excrete mucus. Cats with uterine infection appear clinically healthy, but inside the uterus, the mucus multiplies the cells, causing endometrial hyperplasia. This does not cause clinical disease, but the mucus promotes the growth of bacteria, which multiply and turn the mucus into pus. Symptoms 1. increasing frequency of drinking; 2. frequent urination; 3. loss of appetite; 4. prolonged rest; 5. swelling of the abdomen; 6. normal body temperature; 7. light green, creamy or blood red discharge from the vagina if it is open. Treatment is immediate ovariohysterectomy. This treatment is appropriate for all closed uterine effusions and most open uterine effusions. A breeding female cat with uterine abscesses can be treated with prostaglandins and antibiotics. However, prostaglandins affect many other tissue structures and cause considerable pain to the cat. Second, endometritis is an acute inflammation of the mucous membrane of the uterus in female cats after delivery, and if the inflammation spreads, it can cause myometritis and uterine plasma membrane inflammation. The main causes are obstructed labor, uterine prolapse, fetal clothing, incomplete uterine regeneration, uterine rupture, birth canal injury, emphysema fetus or fetal corruption in the uterus, poor disinfection during assisted delivery, and inflammation caused by bacterial infections such as Salmonella, Brucella, vaginal trichomoniasis and vaginitis. Chronic endometritis is also seen as a cystic hyperplasia of the endometrium. Chronic endometritis generally does not show systemic symptoms. Unproductive cats are still in heat, but are repeatedly infertile, have irregular heat or miscarry or stillbirth within 2-3 weeks after conception. The number of litters is reduced or the signs of estrus are not obvious, the uterine body is enlarged, and the characteristic symptom is the long-term flow of purulent mucus from the vagina. The principle of treatment is to restore uterine tone, increase uterine blood supply, promote uterine contraction to remove its inflammatory exudate, and use anti-inflammatory drugs to eliminate the inflammation of the uterus. Note that pus accumulation in the uterus is a more serious feline gynecological disease and the best way to achieve prevention is to perform birth control on female cats.
