Your mature/senior cat has special needs. Research has shown that special nutrition can proactively help manage common body condition changes associated with aging such as being overweight and loss of muscle mass.
Obesity At least in part due to changes in their metabolic rate, mature cats tend to gain weight despite consuming the same or fewer calories. They can benefit from eating a diet with reduced fat and lower calorie density than regular adult foods.
Loss of Muscle Mass Protein is the building block of muscle. It is important for maintaining muscle tissues, strength and mobility. IAMS research has shown that a higher-protein diet can help older animals maintain muscle mass. By feeding your cat a diet with optimal protein for muscle maintenance, you can help her continue to be active. The protein in a complete and balanced diet also can help support coat health and the natural healing process.
