Collagen supplements are becoming increasingly popular for cats, especially seniors or those with joint stiffness, dull coat, or digestive sensitivity. Felines naturally lose collagen with age, which can contribute to mobility issues and weaker skin elasticity. Studies show that adequate collagen intake may help maintain cartilage resilience and support overall mobility in aging pets.
Let’s break down the best options and how to choose one that fits your cat’s needs especially if you’re considering the best liquid collagen for cats.
We’ll get into the details in a moment.
Key fact : Up to 90% of a cat’s connective tissue is made of collagen, making supplementation especially beneficial for joint, skin, and coat health in senior cats.
