Methods to determine the age of a Korat cat:

1. Look at the hair. Generally, cats with white mixed hair or white beards are elderly cats, and the fur of young cats is softer than that of older cats.

2. Look at the teeth. Cats under four months old have no molars. Cats aged six months have all their teeth. Cats aged three years old have teeth that start to turn yellow. Cats over five years old have obvious dental calculus.

3. Looking at their personality, adult cats are less curious than young cats and their behavior is relatively calm.

4. Look at the eyes. A cat won't open its eyes until 2 weeks after birth. If your cat hasn't opened its eyes yet, it means it's less than 2 weeks old. If the eyes are open, the ears are erect, and there are small teeth, then he is about 1 month old.

5. Look at your weight. Weight can also be used as a reference for judging age. Generally speaking, the older you are, the heavier you are.
