A kitten's growth spurt typically begins around the third month after birth and lasts until about the sixth month. During this period, kittens grow very rapidly, and owners need to provide them with plenty of nutrients to support their rapid development. For example, cooked cat food, canned cat food, beef, chicken, and fish are all excellent choices for promoting healthy growth in kittens.
After a cat's rapid growth phase, its development slows down, and its size growth becomes less noticeable. Generally, a cat's body stops growing around 12 months of age.
