Senior Devon Rex with sensitive stomach and coat thinning

A Devon Rex with a sensitive stomach and thinning coat at 12 — those two things are actually connected more often than people realise. Senior cats generally need higher protein (not lower, despite what some older advice says), reduced phosphorus to support kidney health, and plenty of moisture from wet food. But with a sensitive stomach in the mix, the protein source matters enormously — and coat thinning often points to a gap in omega fatty acids or overall digestibility. To give you a proper steer: what are you currently feeding, and has your vet flagged anything specific like kidney markers or food intolerance?

That picture makes a lot of sense together. Dry food is almost always the wrong call for a cat with borderline kidney values — cats have a very low thirst drive and rely on food moisture to stay hydrated, so switching to wet food alone often makes a visible difference. The weekly vomiting on a dry diet usually means she's eating too fast, the kibble is irritating her stomach, or the protein source just doesn't agree with her. And the coat? Devon Rexes already have a fine, wavy coat that shows nutritional gaps quickly — dullness and thinning at her age usually means she's not absorbing enough omega-3s or the overall diet isn't bioavailable enough. Can you tell me — does she vomit undigested food or does it look more like foam and bile? And is she a fast eater?

Good — that actually tells me the issue is more about eating speed and food type than a deep digestive disorder, which is reassuring. Undigested food brought up quickly is classic rapid eating plus dry food expanding in the stomach. Switching to wet food naturally slows this down because it's denser and more satisfying, and it won't swell up the way kibble does. For a cat with her profile — sensitive stomach, borderline kidneys, coat that needs support, and a Devon Rex's particular nutritional needs — I'd go with Lily's Kitchen Chicken and Duck Senior Wet Cat Food. It's a proper whole-meat recipe with no grains or fillers (which are common stomach irritants), it's lower in phosphorus than most mainstream foods which matters for her kidney picture, and it contains natural oils from the meat and added salmon oil that directly address coat condition. It's also pâté-style, which means slower eating and better digestibility than chunks. Feed it in small portions two or three times a day rather than one big bowl and you should see the vomiting reduce significantly within a couple of weeks.

It's on Amazon UK and in most independent pet shops — straightforward to get hold of. For the vomiting, you should notice an improvement within two to three weeks once she's fully transitioned (do it gradually over a week, mixing with her current food to avoid upsetting her stomach further). Coat changes take longer because the hair growth cycle is slower — realistically you're looking at two to three months before you see real density and shine coming back, but owners often notice the existing coat looking less dull within a month. Given her borderline kidney values, I'd also mention the food switch to your vet at her next check-up — they'll likely be pleased you've moved her to wet food, and it gives them a useful data point when they retest her bloods.

Perfect plan. The combination of wet food, a clean ingredient list, and smaller more frequent meals should make a real difference for her. Devon Rexes are such characterful little cats — it'll be good to see her coat back to its best. Good luck with her.
