What to feed your cat to make its fur shiny?
To achieve a shiny, healthy coat in your cat, you first need to provide them with more protein. This can be achieved by feeding them high-protein cat food, fish, chicken, beef, and egg yolks. You can also supplement their diet with appropriate amounts of lecithin. In addition, proper coat care is essential to further promote a shiny and healthy coat. 
Foods that make a cat's fur shiny
A cat's fur growth requires almost 100% protein, so you can start by switching your cat to a high-protein cat food. Other meat options include fish, chicken, beef, and egg yolks. You can generally feed your cat meat 2-3 times a week.
To make your cat's fur brighter, coat-enhancing products are essential. Lecithin supplements are recommended, as they are quickly absorbed by hair follicles and promote growth. Combining these with a meat-based diet may yield even better results.
In addition to dietary supplements, proper fur care is also very important. Cats need to be bathed with special shampoo products; otherwise, it can damage their hair follicles. Owners also need to brush their cats' fur daily to promote faster hair growth.
