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

Digestive sensitivity in cats is very often down to food intolerance rather than a true allergy — the immune system isn't necessarily involved, it's more that certain proteins or additives simply don't agree with them. Limited-ingredient or novel-protein diets tend to cut through the noise most effectively by removing the likely triggers. To point you in the right direction: what symptoms is your cat showing — vomiting, loose stools, or something else? How long has it been going on? And what are you currently feeding them?
She's 10, a Domestic Longhair, been having loose stools on and off for a few months now. She's on a supermarket mixed variety pack at the moment — chicken, beef, tuna, all sorts in there. I want to switch to something with fewer ingredients but I'd like to buy in bulk to keep costs down.

That mixed variety pack is almost certainly the problem — rotating through chicken, beef, and various additives makes it very hard to identify what's upsetting her, and older cats often become less tolerant of rich or complex recipes. At 10 she's a senior cat, so her digestion is naturally a bit less robust than it was. Before I suggest something, one quick question: has she ever had a reaction to fish specifically, or is fish something she's eaten without issue?
She's always been fine with tuna and fish in general — it's more the chicken and beef ones that seem to cause problems, looking back.

That makes the path pretty clear. I'd go with Applaws Tuna Fillet in Broth — it comes in 70g tins and you can buy a case of 24 on Amazon UK for around £18–£20, which works out very reasonable per meal. The ingredient list is genuinely minimal: skipjack tuna, tuna broth, and nothing else of note. No grains, no additives, no chicken or beef to irritate her. It's high-moisture which is great for a 10-year-old cat's kidneys, and the single protein source means if she does well on it you'll know exactly why. The broth format also tends to be very palatable for cats who've been unwell — it's easy on the stomach and most cats take to it readily.
That sounds ideal actually. Would I need to add anything to it, or is it a complete food?

Applaws tins are marketed as a complementary food, not complete — so you'd want to pair it with something that covers her full nutritional needs. The simplest approach is to use it as the bulk of her diet alongside a small amount of a complete dry or wet food formulated for senior cats. Some owners use a complete senior pâté as a base — something like Purina ONE Senior or even a straightforward complete wet pouch — and top up generously with the Applaws. That way she's getting the benefit of the limited-ingredient protein while still hitting her vitamin and mineral requirements without spending a lot. It's a practical split and keeps costs manageable.
Perfect, that works for me. I'll give that a try and see how her stomach settles.

Give it two to three weeks for her system to properly settle — the first week or so can look a bit mixed as her gut adjusts to the change. Transition gradually if you can, mixing the new food in over about five days. If her stools firm up and she's comfortable, you've found your answer. If things don't improve after three weeks, it may be worth a vet check to rule out anything else going on at her age. Good luck with her — sounds like a straightforward fix once you get the variety packs out of the picture.
