Affordable cat food for sensitive stomachs

Frequent vomiting in a nine-year-old cat is really worth taking seriously — at that age it can become draining for both of you. The good news is that digestive sensitivity in cats is usually down to food intolerance rather than a true allergy, and a limited-ingredient diet with a single protein source tends to make a noticeable difference fairly quickly. Before I point you toward something specific, it would help to know: how often is the vomiting happening — after every meal, a few times a week? How long has it been going on? And what are you currently feeding her?

That mixed-variety approach is actually a very common trigger — rotating proteins and additives keeps the gut in a constant state of adjustment. The fact that this has been going on for a couple of months rather than years suggests it hasn't become entrenched, which is a good sign. Can I ask: does she vomit shortly after eating, or is it more random throughout the day? And is it food coming back up, or more of a foamy bile?

That timing and presentation really does point toward a food intolerance rather than anything more complex — she's likely reacting to an ingredient before it even gets properly digested. The fix is to strip things right back to one protein she hasn't been eating regularly. Given your budget, I'd recommend Applaws Tuna Fillet in Broth — the pouches or tins are well within ten pounds for a multipack, and the ingredient list is genuinely short: tuna, broth, and nothing else of significance. No grains, no additives, no rotating proteins. Tuna is also a novel protein for most cats on supermarket variety packs, which makes it a good reset option. Switch to just this for two to three weeks and watch whether the vomiting frequency drops. Most cats on a simple single-protein wet food like this show improvement within the first week.

With a sensitive stomach cat, a gradual transition over five to seven days is kinder — start by mixing about a quarter of the new food with three quarters of the old, then shift the ratio each day. That said, given that the current food seems to be causing the problem, some owners do go straight to the new food and find the vomiting actually reduces immediately. Either approach can work. The main thing to watch for is any sign of constipation or diarrhoea during the switch, which would mean you've moved too fast. If vomiting continues unchanged after three full weeks on the Applaws alone, that's when a vet visit makes sense to rule out something like hyperthyroidism or kidney issues, which can also cause vomiting in older cats.
