Affordable wet food for senior cat hydration

A 10-year-old Domestic Shorthair on a budget — that's exactly the kind of cat where getting hydration right really matters. Cats evolved in arid environments and have a naturally low thirst drive, so most cats on dry food are chronically underhydrated without their owners realising it. Kidney disease is the leading cause of death in older cats, and wet food is one of the most effective and affordable ways to fight that. Switching to wet food dramatically increases daily water intake — no fancy fountain required. To point you in the right direction: is your cat currently on dry food, wet, or a mix? Does she have any kidney or urinary issues you know of? And have you tried a water fountain at any point?

That's a really sensible place to be — thinking about prevention at 10 is exactly right, because kidney disease often doesn't show symptoms until it's quite advanced. The good news is you don't need to spend a lot. The single most important move is getting more wet food into her diet, and the brand I'd point you to is Felix As Good As It Looks pouches. They're widely available, typically around £10–£12 for a 40-pouch box, which works out to about 25–30p per pouch. Each pouch is roughly 75–80% moisture, so even one or two pouches a day alongside her dry food makes a meaningful difference to her daily water intake. The variety packs keep most cats interested, and at that price point you can afford to feed wet food consistently rather than as an occasional treat.

It's a fair question. Felix isn't a high-meat premium brand, and if your cat had active kidney disease I'd be steering you toward a prescription diet. But for a healthy senior cat where your main goal is increasing hydration and supporting kidney function preventatively, it absolutely does the job. It meets FEDIAF nutritional standards for adult cats, the protein levels are adequate, and the high moisture content is what you're really after here. Where budget brands often fall short is in treats or dry food — but for wet food specifically, moisture is the functional benefit and Felix delivers that. If you ever want to step up slightly without breaking the budget, Purina One wet pouches are a small step up in meat content and still very affordable.

For a standard 4–5kg Domestic Shorthair, one to two Felix pouches a day alongside a reduced portion of dry food is a good starting point. The key is to reduce the dry food slightly when you add wet — so you're not just adding calories on top. A rough guide is to replace about half her dry food with wet. If she's lean, keep her dry food portion closer to normal and add one pouch. If she's carrying a bit of weight, use the wet food to replace dry rather than supplement it. Watch her weight over the first few weeks and adjust from there. The goal is that she's getting a meaningful hit of moisture every single day, consistently.
