Cats with kidney disease need special care, especially with the water they drink. Choosing the right water helps keep them healthy and comfortable.
Kidney disease affects how well a cat’s body removes waste. Cats with this illness need water that supports their kidneys and keeps them hydrated. Plain water is good, but some types help more. Filtered water removes harmful chemicals. Distilled water is very pure but lacks minerals.
Mineral water offers healthy minerals but must be low in sodium. Always check with a vet before changing your cat’s water. Proper hydration can slow kidney damage and improve your cat’s quality of life. This guide explains the best waters for cats with kidney disease and why they matter.
