Research Background and Significance Chronic Kidney Disease (CKD) is a prevalent and progressive condition in felines, significantly impacting animal health and longevity. Despite its frequency, the underlying metabolic disruptions associated with feline CKD remain inadequately characterized, limiting the development of reliable biomarkers and effective therapeutic strategies. Gut-derived uremic toxins and tryptophan metabolism have emerged as critical biochemical pathways implicated in CKD pathophysiology, given their roles in systemic toxicity and inflammation. Metabolomics, the comprehensive analysis of metabolites within biological systems, provides an invaluable approach to elucidate these metabolic alterations. This study leverages high-performance liquid chromatography (HPLC) techniques to profile changes in gut-derived uremic toxins and tryptophan metabolites in feline CKD, offering insights that could advance diagnostic and therapeutic capabilities in veterinary medicine and environmental monitoring. Experimental Design and Methodology The research utilized a robust metabolomics framework centered on validated HPLC met
