This is a specific conversation about Senior cat food — what they need as they age — ask about yours and get one honest answer for your exact situation.

Feeding a 12-year-old Burmilla and a 3-year-old cat in the same home is one of those genuinely tricky situations — they have pretty different nutritional needs, and cats are notorious for eating each other's food. Senior cats like yours typically need higher protein than people assume, reduced phosphorus to protect ageing kidneys, and more wet food to stay hydrated. But the right approach really depends on your Burmilla's current health. Has your vet flagged any conditions — kidney disease, thyroid issues, dental problems? And what are you currently feeding them both?
The vet mentioned her kidneys are starting to show early signs of stress — nothing severe yet, but she said to keep an eye on phosphorus. The younger one is totally healthy. Right now they're both on the same dry food, a mid-range complete adult one, and I just can't manage feeding them in different rooms every single time.

That kidney flag changes things meaningfully — even early-stage kidney stress means you really want to reduce phosphorus now, not wait. Dry food is also the worst option for a cat with kidney concerns because hydration matters so much for kidney function. The tricky bit is your younger cat: low-phosphorus renal food isn't appropriate for a healthy 3-year-old long-term, as it's not nutritionally complete for them. So before I suggest a product — how are you set up at home? Do they eat at the same time, and is there any chance of using a microchip feeder?
I do have one microchip feeder already, actually — I bought it ages ago but never got round to using it properly. They tend to eat at the same time morning and evening.

That microchip feeder is your best friend here — use it for your Burmilla so she gets her own food without the younger one stealing it. For her, I'd recommend Royal Canin Renal wet food pouches. It's specifically formulated for cats with kidney issues — low phosphorus, high moisture, and palatable enough that most cats take to it readily, which matters because cats with kidney stress sometimes go off their food. Your younger cat can stay on a good quality complete wet food or their current diet. The key is: Burmilla eats her renal food in the microchip feeder, younger cat gets fed separately in a bowl at the same time. It takes about a week for them to settle into the routine, but it's very manageable once they do.
That makes sense. Is Royal Canin Renal the best option or are there others worth considering?

Royal Canin Renal is the one I'd start with for early kidney stress — it's the most widely vet-recommended, very palatable, and easy to get on Amazon UK in bulk pouches which keeps the cost down. Hills Prescription Diet k/d is the other strong option and some cats prefer the taste, but it requires a vet prescription in the UK which adds friction. For early-stage, non-prescription Royal Canin Renal is the practical first choice. One thing to do: mention to your vet that you're switching to Royal Canin Renal — they'll almost certainly approve, and it's worth getting a phosphorus recheck in a few months to see if the diet change is helping.
Really helpful, thank you. I'll dig out the microchip feeder and order the Royal Canin.

Good plan. Transition her gradually — mix a little of the new food in with what she's eating now over about a week, as kidney cats can be sensitive to sudden changes. The microchip feeder will make the whole setup much less stressful once it's running. Hope her kidney numbers stay stable — early intervention like this really does make a difference.
