                                                           Body temperatures for kittens and cats do differ.  A normal body temperature, taken rectally, for a cat is between 100° and 102.5°.  A kitten's normal rectal body temperature, when born, is 97°. Its body temperature will increase as the kitten grows, reaching approximately 100° at 4 weeks.
