Cat food for sensitive stomachs: Sphynx advice

Digestive sensitivity in cats is often down to food intolerance rather than a true allergy, and limited-ingredient or novel-protein diets tend to be the most effective fix. For a Sphynx specifically, it's worth knowing the breed can be prone to digestive issues, so getting the diet right really matters. To point you in the right direction: are you seeing loose stools consistently or just occasionally, how long has this been going on, and what are you currently feeding?

Two months of daily loose stools tells me the current food is genuinely not agreeing with her — that's not just a passing stomach upset. Whiskas pouches use a mix of protein sources and quite a few additives, which is a common trigger for cats with sensitive guts. The fact she's fully indoor is also relevant: indoor cats have lower calorie needs and sometimes slower gut transit, which can make digestive sensitivities worse. Does she eat just the one flavour or variety, or does it vary day to day?

That rotating mix of proteins and ingredients is very likely the culprit. Cats with sensitive stomachs often do much worse when the protein source keeps changing — their digestive system never gets a chance to settle. I'd recommend switching her to Royal Canin Sensitivity Control wet food in duck and rice. It's a single, novel protein source that most cats haven't been exposed to, with a highly digestible formula designed specifically for chronic loose stools. It's also nutritionally complete, which matters for a young Sphynx who needs good skin support too — that breed can develop issues if the diet is lacking. One thing: switch gradually over about a week, mixing it in, or you may just get a different kind of upset.

It's widely available on Amazon UK — you can get it in pouches or cans, and multipack boxes work out reasonably priced if you buy in a bit of bulk once you know she tolerates it. Most cats with food-triggered loose stools show a noticeable improvement within two to three weeks of being consistently on the new food, sometimes sooner. If you're seeing no change after four weeks of feeding it exclusively, that's when it's worth a vet visit to rule out something like giardia or IBD. But for a young cat with no other symptoms, a diet change like this resolves it the majority of the time.

The main things to keep an eye on with a fully indoor Sphynx are weight and hydration — wet food like the Sensitivity Control actually helps on both fronts compared to dry. Make sure she has fresh water available at all times, ideally a cat fountain if she's not a big drinker, as dehydration can worsen loose stools. Beyond that, if the stools firm up and stay firm, you're in good shape. The Sensitivity Control is a solid long-term diet for her if it works, not just a short-term fix.
