Hairballs in cats are a common result of grooming. As cats wash themselves, they swallow loose fur, which usually passes through the digestive system without causing any issues. However, some hair can remain in the stomach and form a hairball.
The good news is that there are several ways to help reduce hairballs in cats. Regular grooming, a nutritious diet and good hydration can all support healthy digestion and help swallowed hair move through the digestive system more easily.
