Feeding Two Persians at Different Life Stages

Two Persians at very different life stages is a real feeding puzzle — a 4-year-old in peak adult condition and a 9-year-old heading into senior territory genuinely do need different nutritional profiles, particularly around protein levels and kidney support. Cats are obligate carnivores, so protein quality matters enormously, but the quantity and phosphorus load needs to shift as they age to protect kidney function. Wet food is the right base for both — hydration is critical for Persians, who are already prone to kidney and urinary issues. Can you tell me what you're currently feeding them, and are you managing their meals separately or feeding them together?

That's the right instinct. At 9, your older Persian is at the age where phosphorus restriction and moderate — not high — protein starts to matter for kidney longevity, even before any diagnosis. Your 4-year-old is fine with higher protein to maintain muscle. The main issue with feeding them together is that what's ideal for one isn't ideal for the other. Are you able to separate them at mealtimes, even briefly? And do either of them have any coat or digestive sensitivities? Persians can be prone to both.

Perfect — separating them at meals is genuinely the most important step here, and it sounds straightforward in your case. Here's my recommendation: use Royal Canin Persian Adult wet food pouches for your 4-year-old, and Royal Canin Persian Ageing 12+ — or the Senior range — for the 9-year-old. I'd specifically suggest starting with the Royal Canin Veterinary Care Renal Support wet food for the older cat if you can get it, but if you want something more accessible without a vet prescription, Royal Canin Persian Ageing 12+ in pouches is formulated with reduced phosphorus and adapted protein levels, which is exactly what you need. Both are designed specifically for the Persian facial structure too, which helps with their flat-face eating style. For your older cat, the Royal Canin Persian Ageing 12+ pouches available on Amazon UK are the clearest fit.

No, don't wait. The '12+' label is a marketing threshold, not a biological cliff. A 9-year-old Persian is solidly senior — Persians age faster than many breeds and are more kidney-vulnerable than average. Starting the lower-phosphorus, moderate-protein formula now is proactive medicine, not premature. The formula won't do any harm and could make a meaningful difference to where her kidneys are at 13 or 14. Switch her over gradually across about a week to help with the sensitive stomach, mixing increasing amounts of the new food with the old.

That's a solid plan. One last thing — keep an eye on water intake for both of them, especially the older one. Even on wet food, Persians can be borderline on hydration. A cat water fountain tends to help significantly if you don't already have one. Good luck with them both.
