Solutions for rough cat fur:
1. You can feed your cat lecithin to help it absorb nutrients better and alleviate its hair problems.
2. Regularly brush your cat's fur to prevent it from getting tangled. 
3. You can add a little olive oil to your cat's food, which can help with their coat and gut health.
4. Regularly bathing your cat is also very important. When bathing, you can use a comb to help groom your cat's fur, and when drying, you can use cat-specific fur conditioner to wipe your cat's fur.
5. Meat is very important for a cat's coat. When feeding your cat, make sure the meat is thoroughly cooked, as meat is a food that is very high in protein.
