Best senior wet cat food on a budget

Senior cats — from around 7 onwards — actually need more protein than younger cats, not less, along with reduced phosphorus to protect their kidneys, and wet food is genuinely one of the best things you can do for their hydration. The right food really does depend on what else is going on health-wise, though. How old is your cat exactly, do they have any diagnosed conditions (kidney disease, hyperthyroidism, dental issues, anything like that), and what are you currently feeding them?

Good news — 9 is senior but still early enough that you're ahead of potential kidney issues rather than reacting to them, which is exactly when a switch to wet food pays off most. Before I point you somewhere, a couple of quick questions: does she have any texture preferences you've noticed, or is she a pretty unfussy eater? And roughly how much are you spending on food per month at the moment?

That's a realistic budget for wet food if you go with pouches in bulk on subscribe and save. My recommendation is Applaws Natural Wet Cat Food pouches — the tuna varieties. Applaws is genuinely high in animal protein (around 75% tuna), very low in phosphorus, grain-free, and has minimal filler, which is exactly what a senior cat needs. A 12-pack of 70g pouches runs about £7–8 on Amazon, and with subscribe and save you'll typically get 15% off, which brings the cost per pouch down to under 60p. At one pouch per day — maybe two if she's active — you'd land comfortably within your budget. The tuna broth varieties also add extra fluid, which is the whole point of switching to wet at this stage.

Gradually is always safer, even with an unfussy cat. Mix a small amount of the wet food in with her dry for the first few days, then increase the wet and reduce the dry over about a week. Some cats also get mild loose stools when switching to wet because the higher moisture content changes gut transit — it usually settles within a week. If she's been on dry food her whole life, her kidneys will thank you for the extra hydration almost immediately, and most cats become noticeably more energetic once they're properly hydrated.

Perfect — enjoy saving the pennies. One tip: once she's fully transitioned, keep an eye on her weight. Wet food is more satiating than dry, so some cats naturally eat a bit less and trim down. For a 9-year-old that's usually a good thing, but if she starts looking too lean just bump up to two pouches a day. Hope she loves it.
