Newborn kittens, whose eyes and ears are closed and a little hairy, open their eyes in about 7 ~ 20 days and learn to walk in 9 ~ 15 days. They can eat solid food when they are 4 weeks old and can be weaned around 8 ~ 10 weeks. Kittens can live independently when they are 6 months old, and their life span is about 10 years. Domestic cats living in human families, of course, have a birthday girl who is over 36 years old. Wild cats living in human cities are not so lucky, and their life span may only be a few years.
The life span of domestic cats depends on many factors, such as whether domestic cats have been sterilized, their diet, their feeding methods and environment. These factors and conditions will determine the life span of domestic cats.
Extended data
Generally, domestic cats live longer than stray cats, because stray cats are often in contact with the outside world, so they are more likely to get sick. Frequent illness will naturally reduce the quality of life of cats and shorten their life span.
Sterilized cats live longer than unsterilized cats. If you want to prolong the life of domestic cats, you'd better sterilize them. Sterilized cats will not be troubled by estrus, but also prolong their life and reduce the possibility of urinary system diseases. Diet is also a major factor affecting the life span of domestic cats. Cats who eat natural cat food tend to live longer than those who eat commercial cat food. Because natural cat food has high nutritional value, it is more suitable for cats to eat for a long time.
