Cats are now widely kept as pets by many parents, but many parents do not know much about cats, especially about newborn kittens. Because many parents do not like cat breeding, they do not know much about kittens. Understand, as for what parents need to pay attention to when it comes to newborn kittens, parents still need to understand it, and maybe they will use it in the future.

The cat is blind and deaf when it is born, and cannot keep warm on its own. It also needs the help of the female cat to go to the toilet. A cat's nose doesn't fully develop until it's three weeks old, but it can distinguish its mother's scent as soon as it's born. Kittens sleep very long at this time, so if they are meowing, they are usually too cold, feeling unwell, or hungry. The mother cat will use her tongue to stimulate the kitten's anus so that the kitten will excrete.

Kittens weigh about 100 grams at birth and will double their weight in about two weeks. Kittens under two weeks old have a normal heartbeat of more than 200 times per minute and a breathing rate of about 15-35 times per minute. The body temperature of newborn kittens is low, about 35-36°C, and will slowly rise within 1-2 weeks after birth, until it rises to about 37.7°C when they are four weeks old.

Kittens can feel pain when they are just born, but the neuromuscular reflexes related to pain will not be fully developed until they are 7 days old. The eyes will open 5-14 days after birth. At this time, the iris appears gray-blue, which is the so-called gray-blue eyeball. Over the next few weeks, the eyes will slowly change to the color that the adult cat will have, but kittens will not have enough normal vision until they are about 3-4 weeks old. From the age of 7 to 14 days, they will slowly begin to crawl. On the 16th day, they will begin to waddle and learn to walk. By the 21st day, their steps will become more mature and steady.

Cats usually cannot walk steadily until the third week. Before that, they can only rely on the mother cat to move them. Cats will have their first set of teeth when they are two weeks old, and by three weeks they can basically go to the toilet on their own. Cats at this time will also start to play. Cats that are four weeks old will bite and play with each other, and they will also learn how not to hurt each other. In the fifth week, kittens begin to wean, begin to eat solid food, and become independent. At this time, the cat's sense of balance has been fully developed and it also knows how to groom. This period is a learning stage for cats, where they must learn to understand themselves and other animals.

After a cat is two months old, its muscles are fully developed, but it still needs a lot of exercise to accurately judge distance, height and speed. The skills of hunting were also learned during this period. Generally speaking, it is best for kittens to leave their mothers after they are three months old, because when they are three months old, cats have a sense of territory and a good sense of direction.
