Increased thirst (Polydipsia) often indicates the kidneys have lost the biological ability to concentrate urine, forcing the cat to drink to prevent systemic dehydration.<\/p>\n<p>Actionable Step: Request an SDMA blood test during annual check-ups. SDMA can identify renal decline when only 25% of function is lost, providing a critical window for preventive intervention years before traditional markers like Creatinine.<br \/>\n\t\t\n<style>\n#text-652807848 {\n  line-height: 1.8;\n}\n<\/style>\n\t<\/div>\n\t\n\t<div id=\"gap-276640280\" class=\"gap-element clearfix\" style=\"display:block; height:auto;\">\n\t\t\n<style>\n#gap-276640280 {\n  padding-top: 30px;\n}\n<\/style>\n\t<\/div>\n\t\n<h2><span style=\"color: #f29c9f;\"><strong>Biological Depth: Why the Body Shuts Down<\/strong><\/span><\/h2>\n<div class=\"is-divider divider clearfix\" style=\"max-width:700px;\"><\/div>\n<p><span style=\"font-weight: 400;\">The kidneys are the body&#8217;s primary filtration system.
