Having young kittens in the house is an exciting time, but it's not just a matter of feeding and cleaning up after them. The way you interact with the kittens at a young age shapes how friendly they become as adult cats. When raising newborn kittens, if everything goes well, their mother will do the hard work. Sadly, the unexpected can happen and you may be left hand-rearing the offspring, either because the mother is unable to care for them herself, or she has rejected them. This guide helps you understand the needs of growing kittens in terms of health care, feeding, and socialization.
