Vets agree: hydration is the cornerstone of a cat's kidney and urinary health. Yet many cats instinctively shun still water. Offering fresh, filtered, flowing water encourages their natural urge to drink, a frequent recommendation for senior, spayed or neutered, kibble-fed or cystitis-prone cats.
The material matters too: stainless steel and ceramic are the only truly hygienic options over time. That's the whole point of the Tubby Tabby Stainless Steel Fountain: moving water, oxygenated and purified around the clock, in a stainless steel reservoir that doesn't hold on to bacteria or biofilm.
