Kittens are most vulnerable to death in the first two weeks after birth because they are very fragile and susceptible to various diseases during this stage. Furthermore, if kittens do not receive sufficient maternal immunity after birth, they may also face the risk of death between 6 and 16 weeks of age.
Therefore, to ensure the kittens' health and survival rate, owners should provide a suitable living environment and nutrition, as well as regular vaccinations and veterinary checkups. If the kittens exhibit any abnormal symptoms, they should be taken to the vet immediately.
