1. Genetic factors: The color depth of a plush cat may be influenced by genetic factors. As the cat grows and develops, its fur color may gradually change, manifested as a lighter color.
2. Nutritional imbalance: Lack of necessary nutrients such as vitamins, minerals, or proteins may affect the health and color of cat hair, leading to a lighter color.
3. Sunlight and Environment: Long term lack of sunlight or being in an environment with insufficient light may also affect the pigment synthesis of cat hair, making the color appear lighter. At the same time, certain factors in the environment, such as detergent residues, chemicals, etc., may also cause damage to hair, thereby affecting color.
