You can use the following methods to determine how old an American Curl cat is:

1. Judgment through eyes

When American Curl cats are young, their eyes are clean and clear, smart and cute. However, as American Curl cats enter their old age, their eyes will undergo obvious changes, with jagged mottled spots appearing on their irises, and their eyeballs starting to become cloudy.

2. Judgment by coat condition

With age, the hair of American Curl cats will gradually fade and the amount of white hair will increase. The coat of young American Curl cats is soft and shiny; the coat of older American Curl cats will become more shiny. It's getting darker and rougher to the touch.

3. Judgment by the status of cat’s claws

Generally speaking, as American Curl-eared cats age, their nails and pads will become more and more worn. In addition, American Curl-eared cats’ nails will become thicker and their pads will gradually thicken.

4. Judgment by activity level

American Curl cats in their teenage years are very active and like to play and fight with their own kind. However, as American Curl cats get older, their activity level will gradually decrease and they prefer to stay by themselves.
