A cat's age can be determined in several ways, but none of them will give an accurate answer. The age of a cat can be determined with an error of 2-4 years, and the age of a kitten can be determined much more accurately.
The main most accurate way to determine age, both in kittens and in adult cats, is by her teeth. A special scheme has been drawn up, according to which you can quite clearly determine the age.

By puberty. This method is suitable for kittens. In most cats, puberty occurs by 7-9 months.
By the eyes. In young cats, the eyes are clear, transparent, without discharge. By about age 6, fine lines appear on the lens of the eye.
