White Kitten With Blue Eyes

Birth and development
A feline litter usually consists of two to five kittens. The kits are born after a gestation that lasts between 64 and 67 days, with an average length of 66 days. Kittens emerge in a sac called the amnion which is bitten off and eaten by the mother cat.
For the first several weeks, kittens are unable to urinate or defecate without being stimulated by their mother. They are also unable to regulate their body temperature for the first three weeks, so kittens born in temperatures less than 27°C (80 °F) can die from exposure if they are not kept warm by their mother.
