The most common causes of death in kittens include genetic diseases, malnutrition, low birth weight, and hemolytic disease. In kittenhood, the immune system is not yet fully developed, making them vulnerable and prone to death.

When kittens are young, owners need to take good care of them and provide them with plenty of nutrition to help them grow strong and healthy. Owners also need to vaccinate their kittens when they are young to protect them from germs.
Owners also need to ensure the kittens live in a clean and hygienic environment to prevent bacteria and germs from invading them. Owners should also give their kittens deworming medication regularly.
