In reply to camplate. Hello, thank you for your message. Distilled water does not reliably prevent kidney stones in cats — and in some cases, it might even be less ideal than other types of water. We strongly don’t recommend giving your cat distilled water as their sole source of hydration. It should only be used as an emergency option, for example in cause of natural disasters. Distilled water doesn’t contain any minerals or electrolytes that are essential for our (and feline) bodies. Prolonged digestion of this kind of water could lead to electrolyte imbalances or promote other health issues over time. If you want to prevent kidney stones in your cat, you can do that by assuring your cat has proper hydration and has balanced and appropriate diet. If you would need help with choosing the best possible diet for preventing kidney stones in your cat, we recommend booking a video-call with one of our vets at Pangovet.com and consult your cat’s nutrition. Hope this helps.
