Dehydration related to heat stress is one of the most common preventable causes of death in cats.

No Added Sugar – We listened and made it better. Petralyte Cat Electrolyte and Joint Supplement is now formulated with no added sugar, rebuilt around how cats actually taste and what their bodies need.

Premium Formula – Made with premium, natural ingredients that support hydration, joint comfort and mobility, and recovery for cats of all ages, breeds, and sizes. Includes Nutritional Yeast and Yeast Extract with 5'-Nucleotides for feline-friendly taste; Glucosamine, Chondroitin, and Hyaluronic Acid for joints; Taurine for heart and vision; L-Lysine and L-Glutamine; plus B vitamins, Zinc, Fructooligosaccharides, and Inulin for gut support.
