Because cats are more convenient to take care of and more well-behaved than dogs, more and more people keep pets cats. So are cats easy to keep? Especially for young cat fans, due to various reasons, there are some cases of premature death after cats are born. You can learn and refer to:

Congenital anomalies refer to the abnormal state of kittens at birth, most of which are caused by genetic problems, of course, such as X-rays Or some drugs can also cause teratogenicity. Congenital anomalies of the central nervous system, cardiovascular system, and respiratory system often result in the death of kittens at birth or within 2 weeks, while other congenital anomalies may not be noticed until kittens are fully autonomous.

Some drugs and chemicals can cause teratogenic effects and cause congenital anomalies and premature death in kittens. Therefore, during pregnancy, any drugs and chemicals should be avoided. Chemicals, especially steroids and graymycin, which is used to treat mold.

If a female cat is fed an inappropriate diet, she is likely to give birth to weak or sick kittens, the most serious of which is a lack of oxbilin, which is known to cause Fetal reabsorption, miscarriage, stillbirth, or birth of stunted kittens. Causes of malnutrition in newborn kittens include: severe maternal malnutrition, lack of a proper maternal blood supply in the fetus, or competition for placental space.

The low birth weight of kittens at birth will cause a higher mortality rate. At present, the cause of low birth weight in kittens is not clear, but preterm birth, congenital anomalies or nutritional deficiencies are all common causes. Possible reasons, low birth weight not only causes kittens within six weeks of age to have a higher chance of stillbirth and premature death, but also enough to cause chronic stunting in some kittens, so it is best for kittens at birth to be weighed and measured regularly. , until the age of six weeks.

General domestic cats are less prone to neonatal hemolysis, but purebred newborn kittens are more prone to it. This is because the colostrum of mother cats is rich in transitional antibodies, and the intestines of newborn kittens can only absorb these transitional antibodies within 24 hours. Blood group B cats have strong anti-A alloantibodies. When blood group B female cats give birth to blood group A or AB kittens, the mother cat's colostrum contains a large amount of anti-A alloantibodies. , once the newborn kitten ingests colostrum within 24 hours, these anti-type A alloantibodies will be absorbed into the body and combined with the kitten's red blood cells to dissolve. This hemolysis state will cause a variety of disease. The hemolytic symptoms of newborn kittens mostly occur after ingesting colostrum. Most kittens die suddenly without any clinical symptoms within the first day, but some kittens may have reddish-brown urine or jaundice. and severe anemia continued to worsen and died within one week of age.

According to statistics, the survival rate of kittens is the lowest in the first and fifth births, and the survival rate of kittens born from medium-sized female cats is higher than that of large-sized female cats Or small female cats came high, and the number of 5 had the lowest premature death rate.

The so-called trauma mostly refers to dystocia, cannibalism, or bad behavior of the female cat. Son-eating mostly occurs in neurotic or highly sensitive female cats. It is quite common for female cats to eat sick newborn kittens, but it cannot be blamed on all female cats for son-eating behavior. Such son-eating behavior It is to avoid infection of healthy kittens, and to reduce unnecessary care and breast milk consumption, while mother cats usually ignore and take care of sick newborn kittens, and even take them out of the nest or out of the cage, This behavior is difficult to distinguish from poor motherhood.

Some kittens are not vaccinated due to lack of time or the owner's luck after the birth of one month. Timely medical treatment can also lead to premature death, such as feline plague, infectious peritonitis, etc.
