A kitten's teeth will be fully grown by one month old, and it will begin to replace them with permanent teeth. After one year old, you can observe the wear and tear on the kitten's teeth to determine its age. After six years old, a kitten may grow white whiskers, and after seven years old, it may grow white fur. After ten years old, its motor coordination will decline, and the kitten will become increasingly inactive.
1. Tooth wear
When a kitten is about one month old, its teeth are almost all in. After that, it will continue to lose its baby teeth and grow permanent teeth. When a kitten is over one year old, you can observe the wear on its teeth to determine its age.
2. Morphological characteristics
When asked how to tell how old a cat is, a cat stops growing when it is one year old. Around six years old, it will grow white whiskers around its mouth. At seven years old, it will grow white fur on its back. After ten years old, it will become less active.
3. Motor coordination
Most cats enjoy roughhousing and playing, but when a cat is over ten years old, its coordination will decline due to old age and physical weakness, it will become less and less active, and eventually it will die.
