3 cats, 1 guards the water bowl — fix it

A dominant cat guarding the water source is a really common problem in multi-cat homes, and it's worth taking seriously — the cats being blocked out will often just go without drinking rather than risk a confrontation, which over time raises their risk of kidney disease and urinary problems significantly. The only reliable fix is multiple water stations in separate locations so no single cat can patrol them all. Water fountains are genuinely one of the best things you can do for cat health — moving water is more appealing to cats than still water, and better hydration directly reduces the risk of the kidney and urinary tract disease that shortens so many cats' lives. To point you toward the right setup: are all three cats roughly the same size, do any of them have long fur that tends to get in the water, and do you have a preference on material — ceramic is easier to keep properly clean than plastic?

That's exactly the right instinct — a fountain you actually clean is infinitely better than one that looks impressive but grows biofilm because it's annoying to disassemble. Given you want ease of cleaning and you'll need two units, I'd go with the Drinkwell 360 by PetSafe. It's a circular fountain without a reserved bowl in the middle, so water flows from a central column down into the full ring — that matters here because even your dominant cat can't really "own" a 360-degree drinking surface the way he can a single-spout bowl. It comes apart into just a few pieces, the pump is easy to pull out and rinse, and replacement filters are cheap and widely available. Place one in your kitchen and one in a bedroom or upstairs hallway — somewhere the big cat doesn't patrol — and all three should get reliable access.

A few practical things that make a real difference. First, place the fountains away from their food bowls — cats instinctively prefer not to drink right next to where they eat, it's a wildcat instinct about keeping water sources away from prey. Second, when you first set them up, run them for a day or two near the old water bowl location so the cats discover them easily, then gradually move them to their permanent spots. Most cats take to fountains quickly, especially the curious ones. For cleaning, do a full disassemble-and-wash once a week and replace the filter about once a month — if you get two fountains, just stagger the filter changes so they're not both due at the same time. The Drinkwell 360 filters are around £5-6 each so it's not an ongoing expense worth worrying about.

That should sort the problem completely. Two stations in different rooms genuinely removes the guarding dynamic rather than just working around it — the dominant cat has no incentive to patrol if there's nothing scarce to protect. Keep an eye on whether all three are visibly drinking in the first couple of weeks and you'll know it's working. Good luck with the big lad.
