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.

A 12-year-old Persian from a hoarding situation — you've taken on something really meaningful, and getting her nutrition right from the start is one of the most important things you can do. Senior cats generally need higher protein than people assume, reduced phosphorus to protect the kidneys, and plenty of moisture — wet food is usually the better choice, especially for Persians who are already dehydrated and underweight. But before I point you in a specific direction: does she have any health issues flagged by the vet so far — kidney values, anaemia, anything like that — and what has she been eating since you brought her home?
The vet said her kidney values are borderline but not critical yet. She's been eating whatever I can get into her — mostly cheap wet food pouches. She's very thin, dull coat, low energy. No other diagnosed conditions yet.

Borderline kidneys with severe underweight is a tricky balance — she genuinely needs more calories and protein to recover, but you don't want to overload kidneys that are already under stress. The priority right now is getting weight back on her gently, with a food that's nutritionally dense but also moderately controlled on phosphorus. Can I ask — is she eating willingly at least, or is appetite still a struggle? And roughly how much does she weigh at the moment?
She's eating, which is a relief. She's about 2.8kg — the vet said she should be around 4kg. Appetite is there, she just needs more condition.

Good — appetite working in your favour is a real advantage. With borderline kidneys and significant underweight, I'd point you toward Royal Canin Renal wet food in the pouch format. I know 'renal food' sounds counterintuitive when she needs to gain weight, but the Royal Canin Renal pouches are actually calorie-dense enough to support recovery while keeping phosphorus at a level that won't push those kidney values in the wrong direction. It's also highly palatable — cats with compromised health often take to it well — and the high moisture content is exactly what a dehydrated Persian needs. It's available in chicken and fish varieties on Amazon UK, and most vets are happy for cats with borderline (not yet diagnosed renal disease) to use it proactively. I'd run it past your vet at the next check-in just to confirm, but it's a genuinely sensible fit for her situation right now.
That makes sense. Should I be feeding her small meals frequently rather than one or two big ones?
inparticular.ai
Yes, absolutely — especially for a cat who's been malnourished. Her digestive system has likely been running on very little for a long time, so smaller, more frequent meals are easier to process and less likely to cause vomiting or digestive upset. Four to five small meals a day is a reasonable starting point. As she gains condition and her gut stabilises over a few weeks, you can gradually move toward three meals if that's more practical for you. Track her weight every two weeks if you can — even a kitchen scale works — so you can see the trajectory and catch it early if she plateaus or loses ground.
Really helpful, thank you. I'll get the Royal Canin Renal pouches and start the smaller meal schedule.

You're doing brilliantly by her. A cat that came from a hoarding situation and is still eating and responsive at 12 has real resilience — she just needs consistent, targeted care now. Keep those vet recheck appointments for the kidney values, and if her appetite ever dips or she starts losing weight again rather than gaining, that's the signal to go back sooner. Good luck with her recovery.
