What do you think of the age of a cat? ——A full analysis from teeth, behavior to scientific conversion

In recent years, the breeding rate of pet cats has continued to rise, and how to accurately judge the age of cats has become a hot topic for novices to raise cats. This article will combine the hot discussions on the entire network for the past 10 days, from physiological characteristics, behavioral changes to scientific conversion formulas, and provide you with a structured guide.

1. Determine the age of the kitten by teeth status (0-1 year old)

How to see the age of a cat

7-10 years oldSignificant lens turbidityGray-white hair appearsSignificant decline

3. Characteristics of elderly cats (over 10 years old)

According to the latest research by the International Association of Feline Medicine (ISFM):

  • Severe wear and may be missing
  • Reduce muscle mass by 20%-30%
  • Extend sleep time to 18-20 hours per day
  • 45% of them experience cognitive dysfunction

5. Latest research results in 2023

Research released by the University of Cambridge in September showed that DNA methylation detection can be accurate to ±1.5 years old. This method passes detection:

  • Changes in EPHX2 gene loci
  • TET2 protein expression level
  • Telomer length measurement

6. Reminder of common misunderstandings

1.Inaccurate weight judgment method: Due to the influence of breeds, Maine cats may reach 5kg in their childhood
2.Beard turns white ≠older: It may be caused by stress or nutritional deficiency
3.1 year old ≠ 7 years old: Traditional conversion formulas have been eliminated by modern research

Mastering scientific age judgment methods can not only better meet the needs of cats at all stages, but also timely detect hidden health risks. It is recommended to combine multiple judgment methods and establish health records for adult cats to record changes in important physiological indicators.
