Senior wet food for Russian Blue cats

If you're weighing up grain-free versus standard senior wet food for your Russian Blue, the cost difference is real — and it's worth knowing whether grain-free is actually earning that premium. Senior cats generally need higher protein than middle-aged cats, reduced phosphorus to protect kidney function, and wet food is a great call for keeping them hydrated. But the right formula really depends on what's going on health-wise. How old is your cat exactly, do they have any diagnosed conditions — kidney issues, digestive sensitivity, anything like that — and what are you currently feeding them?

Good news — at 9 with a clean bill of health, you have real flexibility here. Russian Blues are generally a robust breed, but they can be prone to kidney issues as they get older, so keeping phosphorus moderate is worth thinking about even now. Here's the honest answer on grain-free: cats are obligate carnivores and don't need grains, but healthy cats also handle them fine. Grain-free isn't inherently better for a cat with no grain sensitivity — you're mostly paying for marketing. What actually matters is protein quality and quantity, moisture content, and controlled phosphorus. For a healthy 9-year-old, I'd put that money toward a better-formulated standard senior wet food rather than a grain-free one with lower-quality protein.

I'd go with Purina Pro Plan Senior 7+ Chicken wet food pouches. I know she's only 9, but the 7+ formula is appropriate from that age and it's one of the most rigorously formulated senior wet foods available in the UK. It has high-quality chicken as the primary protein, good moisture content for hydration, and Purina's nutritional research behind it is genuinely solid — this isn't a brand coasting on reputation. It's widely available on Amazon UK, significantly cheaper than most grain-free alternatives, and nutritionally it will outperform the supermarket own-brand she's on now. A 16-pouch box typically works out around 60–70p per pouch, which is very reasonable for the quality. It also comes in variety packs if she's picky about flavours, which Russian Blues sometimes are.

Yes — the Purina Pro Plan Senior 7+ variety packs maintain the same nutritional standards across flavours, they're just different protein sources like chicken, salmon, and trout. All are formulated to the same senior spec. Starting with a variety pack is actually a smart move with a fussy cat — you find out which proteins she prefers before committing to a bulk order of one flavour. Once you know what she likes, buying that single flavour in larger quantities brings the cost per pouch down further.

Yes, always worth transitioning over 7 to 10 days — mix increasing amounts of the new food with decreasing amounts of the old. Even if a cat has no known digestive sensitivity, a sudden switch can cause an upset stomach, and fussy cats sometimes refuse food that arrives too differently from what they know. Start with about 25% new food mixed in, and increase every couple of days. If she takes to it well, you can move faster. Russian Blues tend to be creatures of habit, so patience in the first week pays off.
