Solutions to blue cats with yellow hair:

1. You can bathe blue cats regularly, 1 to 2 times a week, and use pet-specific toiletries.

2. If it is caused by diet, adjust the cat’s diet to be light, and then avoid giving the cat oily or salty food.

3. You can also appropriately supplement cats with lecithin, which is a substance that promotes cat hair growth.

4. You can also take the cat to bask in the sun, so that the cat can absorb vitamin D and promote the growth of bright hair.

The reasons why blue cats have yellow hair:

1. It may be that blue cats lack trace elements, lecithin, vitamins and other nutrients that cause the hair to turn yellow.

2. It may also be caused by frequent bathing of cats or failure to use cat-specific toiletries.

3. It may also be caused by feeding cats high-salt and high-fat foods for a long time.
