How to tell the age of a cat by its teeth

Generally, cats that have not yet teethed are usually under 15 days of age. If the cat has already developed the two cusps on the upper and lower jaws and the small incisors on the upper jaw, then this indicates that the cat is 2-3 weeks old. The time for all the milk teeth to come in is around 5 weeks of age. Cats begin to replace their teeth at 2-3 months of age, when all the milk teeth are in place. At 4-5 months of age, cats are at the peak of tooth replacement and it is recommended to provide cats with food that is not too damaging to their teeth to protect their new teeth. In adult cats, age is mainly judged by the wear and tear of the teeth, such as the wear and tear of the lower jaw incisors, but this is generally not very accurate. Cats should normally take good care of their mouths and avoid feeding soft foods for long periods of time to avoid accelerating the formation of dental calculus.
