Help stop late-night hairball hacking in your home with Tomlyn Laxatone Hairball Remedy Catnip-Flavored Gel for Cats. Cats naturally shed their coats, and they will inevitably ingest fur as they groom. Though grooming and bathing your cat helps eliminate loose hair, some fur will still reach their stomach. Your cat’s system cannot digest hair, leading to the formation of troublesome hairballs. These hairballs can lead to blockages within your cat’s digestive system.
