The reason why Maine Coon cats shed so much:
1. When a cat is infected with parasites, it will cause hair loss. The owner needs to deworm the cat in time.
2. When a cat has a skin allergy, it will scratch constantly, causing hair loss. It is necessary to take the cat to a veterinary hospital for treatment. 
3. Cats may also shed fur when they are in a bad mood or under stress. Owners can take their cats out to play to help them adjust their mood.
4. Cats with diabetes may also experience hair loss, and owners should take their cats to the vet for a check-up as soon as possible.
5. Cats will also shed fur if they eat salty food, so you should avoid feeding your cat salty food.
