Cat food for sensitive stomachs

Digestive sensitivity in cats is more often a food intolerance than a true allergy, and limited-ingredient or novel-protein diets tend to work best — though in kittens transitioning to adult food, the issue is frequently simpler than that. A sudden diet change at this age can easily upset the gut before it has time to adjust. To point you in the right direction: is it loose stools specifically, or are you also seeing vomiting? How long has this been happening, and what adult food did you switch to — and how quickly did you make the change?

That timeline makes a lot of sense — three days is quite fast for a switch, especially for a young cat whose gut hasn't fully matured yet. The good news is this sounds like a transition issue rather than an intolerance. What adult food did you move him onto? That'll help me figure out whether the food itself is part of the problem or whether it's purely the speed of the change.

It can, yes. Many own-brand dry foods use higher cereal content and varying protein sources, which gives a sensitive or still-developing gut more to deal with. Combined with a fast switch, you've got two things working against you at once. I'd recommend moving him onto Royal Canin Digestive Care dry food — it's specifically formulated for cats with digestive sensitivity, uses highly digestible proteins, and has a prebiotic blend that supports gut flora. It's also available in a kitten version if you want to keep him on a kitten-appropriate formula a little longer. Either way, reintroduce it slowly over 7 to 10 days: start with 25% new food mixed into 75% of what he's eating now, and increase gradually. That alone tends to resolve cases like this within a week or two.

Given that he's bright, eating well, and it's only been a week with no vomiting or blood, you're fine to try the dietary approach first. If the stools haven't firmed up within two weeks of the slow transition onto Royal Canin Digestive Care, or if you see any blood, significant weight loss, or he becomes lethargic, then get him to a vet. But honestly, what you're describing is a textbook diet-change reaction, and a steady transition onto a more digestible food usually sorts it out without any further intervention.

Perfect plan. Take the full 7 to 10 days — there's no benefit in rushing it. Once he's fully settled on the new food, his stools should firm up noticeably. If things don't improve or you want to revisit whether a kitten formula is better for another month or two given his age, feel free to come back and we can look at that too. Good luck with him.
