Senior Burmese cat feeding in a multi-cat home

A 15-year-old Burmese sharing a home with two younger cats is a lovely setup, but it does create a real feeding challenge — what's right for a senior cat (lower phosphorus, joint support, kidney-friendly formulas) is often quite different from what the youngsters need, and cats are notorious for eating each other's food. Cats generally age more gracefully than dogs, but at 15 your Burmese is well into territory where kidney disease, hyperthyroidism, dental disease, and arthritis are genuinely worth watching. A few quick questions to make sure I point you in the right direction: has your Burmese had any recent vet checks — anything flagged like weight loss, increased thirst, or stiffness? And is the main concern making sure she's eating her own food undisturbed, or are you also trying to switch her onto a senior-specific diet?

That's a really common and frustrating situation — a slow senior with early kidney concerns trying to eat around two food-motivated younger cats. The elevated kidney values make diet genuinely important here, not just a nice-to-have. Low-phosphorus wet food consistently is one of the most impactful things you can do at that stage. But none of that matters if the younger cats are getting there first. Can I ask — are all three microchipped, or just your Burmese?

Perfect — that's exactly what you need for this to work simply. My recommendation is the SureFlap SureFeed Microchip Pet Feeder. It reads your cat's microchip and opens only for her — the lid stays closed when either of the younger cats approaches. No collar tags, no programming headaches. You place it somewhere slightly separate, and your Burmese can eat at her own pace without competition. You'd get one for her, keep the younger two on standard bowls elsewhere. It's not cheap, but for a cat with early kidney disease where consistent controlled feeding actually matters medically, it's genuinely worth it. The Connected version also lets you log how much she's eating, which is useful data to bring to vet appointments given where her values are.

For most people the standard SureFeed is enough — it does the job of keeping other cats out reliably and costs less. But given that your vet is already monitoring kidney function, the Connected version has one practical advantage: it tracks her daily food intake and shows you trends over time. Unexplained appetite changes are often one of the first signs kidney disease is progressing, and having actual data rather than 'she seemed to eat less this week' is genuinely useful at vet check-ins. If budget's a consideration, start with standard. If you want that monitoring layer, the Connected is worth it. Either way, the core microchip function is the same.

At the 'elevated but not critical' stage, most vets recommend a high-quality senior wet food with controlled phosphorus rather than jumping straight to prescription renal diets — though follow whatever your vet advised specifically. Royal Canin Renal wet food is widely used once values are confirmed, but if the vet hasn't prescribed a renal diet yet, a good senior wet food like Hills Science Plan Adult 7+ or Royal Canin Senior Instinctive in pouches keeps phosphorus lower than standard adult food and keeps her well hydrated, which matters a lot for kidneys. Wet over dry is the consistent advice for cats with any kidney concern — hydration does real work there. Bring the food question back to your vet at the next check given her values, but moving to a senior wet formula now is a sensible step either way.
