A kitten (Old English diminutive of cat) is a juvenile domesticated cat (Felis catus) that is not yet fully-grown.
Kitten is also an alternative name for the young of some rodents, such as rats, rabbits, hedgehogs, beavers, squirrels and skunks.
The young of big cats are called cubs rather than kittens. Either term may be used for the young of smaller wild felids such as ocelots, caracals, and lynx, but "kitten" is usually more common for these species.
A kitten opens its eyes for the first time.
A litter of kittens usually consists of two to five kittens. They are born after a gestation that lasts between 64–67 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.
The mother's milk is very important for the kittens' nutrition and proper growth. This milk transfers antibodies to the kittens, which helps protect them against infectious disease. Newborn kittens are also unable to produce concentrated urine, and so have a very high requirement for fluids.
Kittens open their eyes about seven to ten days following birth. At first, the retina is poorly-developed and vision is poor. Kittens are not able to see as well as adult cats until about ten weeks after birth.
Kittens develop very quickly from about two weeks of age until their seventh week. Their coordination and strength improve, they play-fight with their litter-mates, and begin to explore the world outside the nest or den. They learn to wash themselves and others as well as play hunting and stalking games, showing their inborn ability as predators. These innate skills are developed by the kittens' mother or other adult cats bringing live prey to the nest. Later, the adult cats also demonstrate hunting techniques for the kittens to emulate.
