Why do newborn kittens die?
1. Reasons why newborn kittens are prone to death
Newborn kittens are weak and prone to illness, as their immune systems are not yet fully developed, making them susceptible to various diseases such as pneumonia, diarrhea, and bacterial infections.
In addition, the mother cat's diet and hygiene directly affect the kittens' health. If the mother cat is malnourished or has an infectious disease, it can be passed on to the kittens, increasing their risk of death. 
2. Lack of sufficient nutrition
After giving birth, the mother cat needs a lot of energy and nutrients to support her kittens' growth and development. If the mother cat's diet is insufficient or lacks necessary nutrients, it can lead to problems such as stunted growth and weight loss in the kittens.
In addition, some cat owners are prone to improper feeding when raising kittens, such as overfeeding or feeding them an unbalanced diet, which can lead to various diseases in kittens and increase the risk of death.
3. The effects of high and low temperatures on kittens
Kittens have a poor ability to adapt to temperature changes and are easily affected by extreme temperatures. In hot weather, kittens are prone to death from dehydration and heatstroke; while in cold environments, kittens are susceptible to respiratory infections or hypothermia.
4. Kittens are physically weak and easily injured.
Newborn kittens are vulnerable to injury due to their small size and delicate bodies. Lying still for extended periods can compress their hind limbs and spine, leading to spinal deformities and limb disabilities. Excessive petting or mishandling can also cause injury to kittens.
Therefore, taking care of kittens requires special care, including providing them with regular exercise and massages to ensure their health.
