Optimal Care for Indoor & Senior Cats

Cats have unique metabolic and physiological needs that change dramatically as they age. Whether you have an active outdoor roamer or a cozy indoor senior, our tools focus on these critical care areas:

  • ● Cat Nutrition: Feline obesity is the #1 health issue for domestic cats. Managing calorie intake is essential to preventing diabetes.
  • ● Indoor Cat Care: Indoor cats burn significantly fewer calories. Our calculator adjusts portions specifically for their sedentary lifestyle.
  • ● Senior Cat Health: Older cats (11+) need careful weight monitoring to catch early signs of kidney disease or hyperthyroidism.
