Cat hydration for indoor dry-food cats

A 6-year-old indoor cat on dry food is actually one of the most common setups I see when it comes to hydration problems — and it's worth taking seriously. Cats evolved in deserts and have a naturally low thirst drive, which means they rely on food moisture to stay hydrated. On dry food alone, most cats are chronically underhydrated, and that quietly puts pressure on the kidneys year after year — kidney disease is the leading cause of death in older cats. Water fountains and wet food are the two most effective ways to fix this. Before I point you toward anything specific: does your cat have any history of kidney or urinary issues, and have you ever tried a water fountain with her?

That's really typical behaviour, and it's not indifference — it's biology. Cats are hardwired to distrust still, stagnant water (in the wild it signals contamination), so a static bowl is always going to be a tough sell. Moving water triggers their instinct to drink. A fountain can genuinely transform intake overnight for cats like yours. Can I ask a couple more things? Is she a grazer — does she have dry food available all the time — or does she eat at set mealtimes? And how big is the flat, roughly? I'm thinking about where a fountain would realistically live.

Perfect, that gives me a clear picture. For a flat setup like yours — compact space, one cat, kitchen placement — the Catit Flower Fountain is the one I'd go with without hesitation. It holds 3 litres, which means you're not constantly refilling, and the flower-top design creates a gentle triple flow that most cats find irresistible — particularly cats who've been ignoring still bowls. The filter catches hair and debris, which matters more in a kitchen. It's quiet enough that you won't notice it, it's easy to disassemble and clean, and it's consistently one of the best-reviewed fountains in the UK for good reason. One thing worth doing alongside it: start adding a tin of wet food in the evening, even just half a pouch. At 6, getting ahead of kidney stress is much easier than managing it later.

It's one of the simpler ones — the flower top and base separate easily, the pump lifts out, and all the main parts are dishwasher safe. I'd say a proper weekly rinse and a full clean every two to three weeks is all it needs. Replace the filter roughly once a month. The filters are cheap and widely available. Honestly, once you've done it twice it takes about five minutes. The bigger ask is just keeping it topped up — 3 litres goes faster than you'd expect if she starts actually using it, which is a good sign.

Yes — don't replace the old bowl straight away. Put the fountain in the kitchen as planned, leave her existing water bowl out too, and let her approach the fountain on her own terms for the first few days. Most cats investigate within 24 hours. Once she's drinking from it regularly, you can remove the bowl. Some people also put a small piece of treat near the fountain the first day just to get the cat close — after that the sound and movement usually does the rest. You're in a really good position to get ahead of this before any issues arise. Six is still young for a shorthair.
