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. 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
Kittens need extra care
Kittens require a high-calorie diet that contains more protein than the diet of adult cats. From weaning until about one year of age they should be fed a diet specifically formulated for kittens. Kittens can be touched or held when a lot of fur is visible and kittens are walking. Most veterinarians recommend that kittens be vaccinated against common illnesses beginning at 2-3 months of age (FVRCP 8 weeks; FVRCP 12 weeks; FVRCP, rabies and sterilization at 16 weeks) and spayed or neutered at approximately 7 months of age. Some veterinarians will spay or neuter kittens as young as 7 weeks and weighing at least 2 pounds. The practice is particularly common in animal shelters. Such early spaying does not appear to have any long-term health risks to cats, and may even be beneficial in male cats. Kittens should also be wormed against roundworms at about 4 weeks.
