This is a specific conversation about Cat food — getting it right — ask about yours and get one honest answer for your exact situation.

Feeding a senior cat and a kitten under the same roof is one of the trickiest multi-pet situations — their nutritional needs are genuinely at opposite ends of the spectrum, and most people end up either compromising or exhausted from policing mealtimes. Before I suggest the best approach, it helps to know a bit more: how old is each cat, are there any health issues with either of them — especially kidney or joint concerns in the senior — and what are you currently feeding both of them?
The senior is 13 and pretty healthy so far, the kitten is about 4 months. I've been feeding them both the same kitten food because I read kittens need more calories and I panicked about the kitten not getting enough. The senior seems fine but I'm not sure it's right long term.

Your instinct is right to question it. Kitten food is high in protein and calories, which is fine for a growing kitten but harder on an older cat's kidneys over time — and senior cats need different phosphorus levels, joint support, and often better hydration through wet food. The good news is your 13-year-old isn't in crisis from this, but you do want to course-correct. Is the kitten able to physically access separate spaces, or do they tend to eat from whichever bowl is nearest?
They eat near each other and the kitten absolutely steals from the senior's bowl if I'm not watching. The senior doesn't seem to fight back at all.

That's very common — kittens are relentless and seniors often just step aside. The most practical solution isn't trying to supervise every meal; it's using a microchip-activated feeder for your senior so only they can access their food. That removes the stress entirely. For the food itself, I'd put your senior on Royal Canin Ageing 12+ wet pouches — they're specifically formulated for kidney support, easy to digest, and lower in phosphorus, which is exactly what a 13-year-old cat needs. The kitten stays on kitten-specific wet food. Wet food for both is the right call — cats are poor drinkers and kidney disease is the number one killer of older cats, so hydration through food matters enormously. Does your senior currently eat wet or dry?
Mostly dry with some wet mixed in. I've been using Whiskas kitten pouches for both of them which feels wrong now that you put it like that.

It's an easy mistake and you've caught it at a good time. I'd transition your senior fully to Royal Canin Ageing 12+ wet pouches — do it gradually over about a week, mixing with the current food so their digestion adjusts. Keep the kitten on a good kitten wet food, something like Royal Canin Kitten pouches or Animonda Carny Kitten so their needs are matched too. The microchip feeder I'd recommend is the SureFlap SureFeed — it's the best one available in the UK, reliable and easy to set up, and it will completely solve the bowl-stealing problem without you having to stand guard at every mealtime.
That actually sounds really doable. I didn't realise a microchip feeder was even a thing. Will my senior cat's existing microchip work with it?
inparticular.ai
Yes — the SureFeed reads any standard ISO 11784/11785 microchip, which is what all UK-registered cats have. You just hold your cat near it once during setup and it learns their chip. No additional tags or collars needed. Get the senior on Royal Canin Ageing 12+ wet pouches, the kitten on kitten-specific wet food, and use the SureFeed for the senior's bowl. That combination solves the nutrition mismatch and the theft problem in one go.
