Generally speaking, the cheek growth stage of blue cats is when they are 7 or 8 months old, and the cheek growth lasts until about 2 years old before it is completely formed. Blue cats are a cat breed that is more likely to have gills, but a cat's gills are also affected by genes and appearance. Male cats will have gills better than female cats. ​​​​​​

Secondly, if you want your blue cat’s hair and gills to look better, you can feed your cat some protein-rich meat, such as beef, chicken, fish, venison, etc., to supplement your cat with high-quality protein and fat. There are also some nutritional supplements that can help cats grow their cheeks better.

Finally, to make blue cats have hairy cheeks, you need to increase sleep and reduce strenuous exercise, otherwise the cat’s energy will be consumed. Therefore, after the cat has eaten and drank enough, let the cat rest well so that the body can better absorb nutrients.
