Question

Kittens are unable to regulate their body temperature for how long after birth?

Answer 1

Kittens are unable to regulate their body temperature for the first two weeks after birth. During this time, they rely on their mother's body heat and the warmth of their environment to keep warm. After two weeks, they will begin to develop the ability to regulate their own body temperature.

Answer 2

Because kittens cannot self regulate their body temperature until about four weeks of age, ambient temperature can significantly affect their survival. Without mom to keep them warm, body functions may begin to shut down as their core temperature decreases. Kittens should feel warm when you pick them up.
