The age of a cat can be determined by its teeth, weight, hair, and eyes. First of all, the teeth are mainly judged by the degree of wear, color, and appearance. The teeth of older cats are yellower and may be chipped, while the teeth of kittens are whiter. Secondly, kittens weigh significantly less than adult cats, and kittens are smaller while adult cats are larger. In addition, the hair of kittens is thicker and more shiny than that of older cats, while the hair of older cats is rough and messy. Eventually, a kitten's eyes will look very clear and clear, whereas in older cats the eyeballs will be very cloudy.

1. Distinguish through teeth

The most effective way to tell the age of a cat is to look at the number and condition of the cat’s teeth.

First place, number of teeth. Cats begin to grow teeth about 2 weeks after they are born. They have 26 teeth at about 4 months old. Cats now have no molars. When cats are over 6 months old, 4 molars will grow. Now cats have 30 teeth.

Second, the condition of the teeth. If the cat’s teeth are white and transparent, it means it is still a kitten. The cat’s teeth will start to show wear and tartar at the age of 1. The older the cat, the more serious the degree of tooth wear and tartar will be.

Note: It is easy to determine the age of a cat based on its teeth for underage cats, but it is more difficult to determine the age of an adult cat based on its teeth because the changes in its teeth are not obvious.

2. Distinguish by weight

Kittens weigh 100~120g when they are born, about 170~230g at 1~2 weeks, 300~350g at 2~3 weeks, 350~400g at 3~4 weeks, 400~ at 4 weeks~2 months About 700g, which is about 2 to 4 pounds in 3 months. The standard weight of small cats as adults is about 5 to 10 kilograms, the standard weight of medium-sized cats is about 8 to 13 kilograms, and the standard weight of large cats is about 10 to 25 kilograms.

However, the specific weight of cats will vary depending on the individual and gender. Generally, the weight of male cats will be heavier than that of female cats, and they will increase faster.

3. Identification through hair

Based on the thickness of the cat’s hair and sebum, you can determine whether the cat is an old cat or a young cat.

First of all, observe the hair. Young cats generally have smooth and shiny hair, which is very soft to the touch. In old age, cats' hair will be rougher and darker, and some will grow gray and white miscellaneous hairs. It is particularly noticeable on black cats, and usually begins to fade in cats aged 12 to 14 years old. Secondly, young cats have thicker subcutaneous fat, while older cats have thinner subcutaneous fat.

4. Distinguish through eyes

About 2 weeks after the cat is born, the eyes will gradually open. If the cat hasn't opened its eyes yet, it means it is less than 2 weeks old. If the eyes are open, the ears are erect, and there are small teeth, the baby is about 1 month old. In addition, the eyes of younger cats are clear and transparent, while the eyes of older cats will begin to become dull and dirty.
