Best water fountain for hairball-prone cats

A senior British Longhair who's both hairball-prone and underhydrated — that's a combination where getting more water into her really does matter. Better hydration helps move hairballs through the digestive tract more smoothly, and at nine years old, protecting kidney function becomes a genuine priority. Water fountains are one of the best things you can do here because cats are instinctively drawn to moving water and will simply drink more of it. Before I point you toward a specific fountain, can I ask: is this just for her, or do you have other pets too? And does she eat mostly dry food, wet food, or a mix? That'll help me make sure I'm pointing you at the right flow rate and size.

That's really useful — and honestly the plastic fountain experience is very common with British Longhairs, who tend to be sensitive to taste and smell. Plastic can leach odours over time, which cats detect even when we can't. The fact she's on mixed feeding is good; wet food helps with hydration already, but a fountain will top that up meaningfully throughout the day. Given her age, her hairball tendency, and that she's already rejected plastic, I'd go straight to ceramic. Can I ask one more thing — does she prefer drinking from a wide bowl style, or has she ever shown interest in a running stream or tap?

That tap behaviour is a really clear signal — she absolutely wants moving water, she just hasn't had the right fountain yet. My recommendation is the Petkit Eversweet Solo 2 Ceramic Pet Fountain. It's a wide, shallow ceramic bowl with a gentle flow across the surface rather than a tall jet, which suits cats who like the tap-drip style. The ceramic construction means no plastic taste or smell, it's straightforward to disassemble and clean (important for a long-haired cat whose fur will inevitably get into the water), and it runs very quietly so it won't put her off. The filter system handles fur and debris well, which matters with a British Longhair. For a single senior cat with her specific needs — hairballs, low hydration, fussiness about materials — this is the one I'd buy. It's available on Amazon UK and the replacement filters are easy to find.

The filters typically last around 2–4 weeks depending on how much fur ends up in the water — with a British Longhair, probably closer to two. The fountain itself should be fully disassembled and washed weekly; the ceramic surfaces wipe clean very easily compared to plastic, which tends to develop a biofilm that's hard to shift. The motor unit is small and simple to rinse. It's genuinely one of the easier fountains to maintain, which matters because a fountain that's a chore to clean is one that doesn't get cleaned — and a dirty fountain is worse than no fountain for a cat with health concerns. Set a weekly reminder and it becomes a quick ten-minute job.

Yes, it's realistic — with a clear caveat. Better hydration helps the digestive tract move hairballs through more efficiently, so you should see fewer vomited-up hairballs over time. It won't stop hair being swallowed, but a well-hydrated gut handles it much better. If she's bringing up hairballs very frequently despite good hydration, it's worth mentioning to your vet, as there are also hairball-support diets and occasional malt paste supplements that work alongside a fountain rather than instead of it. But as a foundation step for a nine-year-old British Longhair, a ceramic fountain with good water flow is absolutely the right move.
