Stages Of Development For Cats

Similar to a human’s stages of development, cats go through these stages of growth before they attain maturity;

  • 0-2 MONTHS – this is the infancy period of a kitten, and it is of the utmost importance that it is spent with the mother. During this time, the mother feeds the cat with her milk, and the kitten learns to adapt to the environment.
  • 2-3 MONTHS – this is the period during which most kittens are adopted and separated from their mothers. It marks their evolution from a liquid to a solid diet. Moreover, it is required that you provide your kitten with the most attention during this stage as it can be a traumatic and emotional period for them. During this time, your cat may gain 2-4 pounds of weight.
  • 3-6 MONTHS – this is the adolescent period for your cat, and when it is going through “puberty”. As in humans, your cat may become more destructive and experience mood swings, but it is all part of maturity so don’t be alarmed. Also, most veterinary doctors recommend that you get your cat neutered when they become 6 months old.
  • 6-12 MONTHS – this can be regarded as the young adult period of a cat’s lifetime. During this time, the cat will usually attain its full size, and weigh 8-15 pounds, however, this depends on the breed of the cat.
  • 1-2 YEARS – most cats will stop growing at the age of 18 months, and they attain their maximum size. However, some cats might continue to grow even after this time, but not as hastily. On average, a cat’s weight should be twice the weight it has when it is 16 weeks old.
