This is a specific conversation about Cat hydration — getting cats to drink more — ask about yours and get one honest answer for your exact situation.

Your vet gave you solid advice — for an 8-year-old Ragdoll with early kidney concerns, switching to wet food is genuinely one of the most impactful things you can do. Cats evolved in arid environments and have a very low thirst drive, which means most cats on dry food are chronically underhydrated. Over time, that puts real strain on the kidneys, and kidney disease is the leading cause of death in older cats. Wet food quietly boosts hydration with every meal, which helps the kidneys flush waste more efficiently. Before I point you toward something specific — is your Ragdoll currently on dry food only, or already getting some wet? And has your vet mentioned anything about phosphorus restriction yet?
She's on dry food only at the moment. The vet mentioned her kidney values are slightly elevated but not at the stage where she needs a prescription diet. They just said adding wet food would help slow things down.

That's actually a really good position to be in — catching it early means wet food can do a lot of work before you'd ever need to escalate to a full renal prescription diet. At this stage, the priority is hydration and keeping phosphorus moderate, without necessarily going full therapeutic yet. Can I ask — does she have any strong food preferences? Some cats are texture fickle, especially Ragdolls who've only ever had kibble. Knowing whether she tends to be picky will help me point you toward something she'll actually eat consistently.
She's never had wet food before so I'm not sure. I'd rather start with something that's well tolerated and not too rich, since I don't want to upset her stomach.

Perfect — that's exactly the right instinct. For a first-time wet food cat with early kidney concerns, I'd go with Royal Canin Renal wet food pouches in gravy. It's specifically formulated to support kidney function with controlled phosphorus, high-quality protein, and added moisture — and the gravy format tends to be well accepted by cats moving from dry food because the texture isn't too far a jump. It's not a prescription product, so you don't need a vet sign-off to buy it, but it's formulated with renal support in mind. Start with one pouch per day alongside her usual dry food, and you can gradually increase the wet proportion over a week or two so her digestion adjusts. Royal Canin Renal wet pouches are widely available on Amazon UK — look for the multipack in either chicken or fish varieties.
That sounds really sensible. Should I be trying to phase out the dry food entirely or is mixing fine long term?
inparticular.ai
Mixing is absolutely fine long term, and honestly it's what most vets would suggest at this stage. You don't need to eliminate dry food entirely — the goal is simply to increase her daily moisture intake meaningfully. Aim for at least 50% of her calories coming from wet food if you can, but even 30–40% makes a real difference to kidney filtration. If her values are only slightly elevated, that shift alone can genuinely slow progression. One thing worth adding: a water fountain alongside the wet food is a nice second layer of support. Cats are much more likely to drink from moving water, so even a modest fountain can bump up hydration further. But the wet food is the bigger win — start there.
Brilliant, thank you. I'll order the Royal Canin Renal pouches and see how she gets on.

Great choice — give it a week or two for her to settle in, and don't worry if she's cautious at first. You can try warming the pouch slightly in warm water (not the microwave) to release the aroma, which often helps first-timers come round. Keep an eye on her next blood test and you may well see a positive shift. You're doing exactly the right thing by acting early — her kidneys will thank you.
