Hill's Science Diet Hairball Control Senior 7+ Chicken - Hairball

Our review of Hill's Science Diet Hairball Control Senior Adult 7+ finds it best suited for older cats that struggle with frequent hairballs and need a maintenance formula that supports coat and lean muscle. The single biggest reason to buy is its focused nutrition to help reduce hairball formation while providing targeted support for seniors, including taurine for heart and kidney health. In testing and from customer reports, the formula is palatable and made with quality protein and natural ingredients, offering a practical daily food for cats past seven years that sheds or grooms heavily.

Key Features

• Hairball control: The recipe includes nutrients formulated to help avoid hairball formation in mature cats, lowering visible hairball events for many pets.
• Essential fatty acids: Omega-6s and omega-3s plus vitamin E work together to nourish skin and support a healthier, shinier coat.
• High quality protein: Protein supports maintenance of lean muscles important to senior cat mobility and overall condition.
• Taurine support: Added taurine helps maintain heart and kidney health that become more important with age.
• Trusted manufacturing: Made in the USA with global ingredients, offering traceability and quality control that owners value.
• Veterinarian recommended: Hill's is widely recommended by veterinarians, which adds confidence for owners choosing a therapeutic-lean daily diet.

Who It's For

This food is aimed at cat owners with senior cats aged 7 and up who experience frequent hairballs or heavy shedding and want a maintenance diet that addresses coat health and muscle preservation. It is well suited for owners who prefer a veterinarian-recommended brand and a dry kibble formulated with taurine and balanced fatty acids for aging cats.

Owners whose cats have severe, ongoing digestive intolerance or who require a veterinary-prescribed therapeutic diet for a specific medical condition should consult their veterinarian and may need a different formula. Also, if a cat consistently rejects larger kibble sizes, consider trying a smaller-kibble senior formula or a wet food alternative.
