Switching a Persian cat to wet food at 9

Switching a Persian from dry kibble to wet food at nine is actually a really smart move. Senior cats generally need more protein than younger cats, not less, and wet food makes a big difference for hydration — especially for Persians, who are prone to kidney issues. The right wet food depends on whether your cat has any existing health conditions, though. How is she doing healthwise — any kidney concerns, digestive sensitivity, or weight issues? And what kibble are you currently feeding her?

Mochi is a great name. Being preventative about kidney health is exactly the right instinct — by the time a diagnosis comes, there's already been some damage, so supporting kidney function early through diet makes real sense. Since she's a healthy weight and has no digestive issues, you've got flexibility. The main things to look for in a wet food are high-quality animal protein, low to moderate phosphorus, and no unnecessary fillers. What's your rough budget per month for food, and are you happy to do a gradual transition over a couple of weeks?

In that case I'd go with Hill's Science Plan Adult 7+ Youthful Vitality wet food pouches — the chicken and vegetable variety. It's formulated specifically for cats from seven onwards, with controlled phosphorus to support kidney health proactively, high protein from real chicken, and added omega-3s which are genuinely useful for ageing cats. It's also a pâté texture, which tends to suit Persians well since they can be fussy about chunky gravies. For the transition, mix about 25% wet into her current kibble for the first few days, then 50/50 by day five, then 75% wet by day ten, and fully wet by day fourteen. Mochi's digestive system will handle it better that way even if she shows no signs of sensitivity.

For a cat like Mochi — nine years old, Persian, preventative kidney focus — I'd go fully wet if she takes to it well. The hydration benefit is significant and ongoing, and at her age that matters more than any minor dental benefit dry food might offer. If she ever goes through a phase of rejecting the wet food, having a small amount of a low-phosphorus dry as a backup is fine, but it shouldn't be the main event. Once she's fully transitioned, keep an eye on her water intake and litter tray output — more dilute urine is a good sign the wet food is doing its job.

Good choice. Mochi is lucky to have someone thinking ahead for her. One last thing — once she's been on wet food for a few months, it's worth asking your vet for a routine kidney panel blood test. It gives you a baseline, so if anything does shift in future years you'll have something to compare against. Enjoy the transition — most cats take to wet food pretty quickly once they get a taste for it.
