Best food for senior cats with sensitive digestion

A 14-year-old Cornish Rex with a sensitive stomach is a combination worth taking seriously — senior cats generally need higher protein, lower phosphorus for kidney health, and plenty of moisture, but when digestive sensitivity is in the mix, the source and digestibility of that protein matters just as much as the amount. To point you toward the right food, it helps to know: has your vet flagged any specific conditions like kidney disease or IBD, and what are you currently feeding her?

Switching to wet is a really sensible move at 14, even without kidney disease — hydration becomes harder for older cats to manage and wet food takes that pressure off. For a cat with her history, you also want to avoid rich proteins or complex ingredient lists that give sensitive guts more to deal with. What protein is she currently eating — chicken, fish, something else?

Chicken is usually a safe starting point for sensitive cats, which is helpful. The fact she's leaving it sometimes is also worth noting — palatability often drops in older cats, and wet food tends to be more appealing. Given everything — age, sensitivity, no kidney diagnosis but worth keeping an eye on phosphorus — I'd go with Royal Canin Sensitivity Control wet food in the chicken and rice pouches. It's formulated specifically for digestive sensitivity, uses a single highly digestible protein, and the rice component is gentle on the gut. It's not a senior-specific label but it fits her needs better than most foods that are. Transition slowly over 7–10 days mixing it in, and you should avoid the loose stool flare-up she gets with changes.

It's worth being mindful rather than alarmed. Kidney function does decline gradually in most cats from around 12 onwards, and keeping phosphorus moderate is a sensible preventive step — you don't need a prescription renal diet, but avoiding high-phosphorus foods like fish-heavy options is reasonable. The Royal Canin Sensitivity Control is not elevated in phosphorus, so it fits well. Ask your vet to run a basic renal panel at her next check-up if they haven't recently — catching any early changes means you can adjust diet before problems develop.

That's exactly the right plan. Start the transition gradually and she should settle in well — most sensitive cats do much better on a consistent wet food once they adjust. Good luck with her, and do check back if you want to revisit once you have the vet results.
