Cat food for bloating & sensitive stomachs

Digestive sensitivity in cats is often down to food intolerance rather than a true allergy, and limited-ingredient or novel-protein diets tend to work best. Bloating in particular can point to fermentable ingredients or eating too fast — both worth unpicking. To get a clearer picture: how long has the bloating been happening, is it accompanied by any vomiting or loose stools, and what is he currently eating? Also — you mentioned a younger cat who steals food, so I'll want to understand how feeding time works in your house.

That four-month timeline and the mix of wet and dry from different brands is useful — inconsistent protein sources can quietly irritate a sensitive gut. Felix pouches in particular contain a lot of gravy, fillers and varied ingredients that aren't ideal for a cat prone to bloating. The food-stealing dynamic matters too: if Milo is eating Bjorn's food, Bjorn may also be eating faster than he'd like, which contributes directly to bloating. Can you tell me a bit more about how you feed them — same room, same time, free-fed dry during the day?

That's a classic multi-cat feeding problem and it's almost certainly making Bjorn's bloating worse — he's either rushing to eat before Milo gets there, or Milo is finishing his portions and Bjorn is going without and then overeating later. Before we even get to the food itself, I'd strongly suggest feeding them in completely separate rooms with the door closed, even just for mealtimes. It only needs to be ten minutes. That one change alone often reduces stress-eating and bloating significantly in the older cat. On the food side, I'd simplify Bjorn's diet considerably — one consistent, digestible food rather than mixing brands.

For Bjorn I'd go with Royal Canin Digestive Care dry food. It's formulated specifically to support digestive comfort — highly digestible proteins, a controlled fibre blend that firms up soft stools without being harsh, and it's consistent in its ingredients so you're not introducing new proteins every bag. For an 8-year-old Norwegian Forest Cat with bloating and occasional soft stools, it's a well-matched choice. I'd drop the Felix pouches entirely and if you want to add wet food, use Royal Canin's own pouches so the protein source stays consistent. Give it six weeks — bloating from dietary inconsistency usually settles within that window once the gut stabilises.

Royal Canin Digestive Care is fine for healthy adult cats — it won't harm Milo if he gets into it occasionally. That said, once you're feeding separately, the goal is for each cat to eat their own portion in full, so it should mostly be a non-issue. If Milo has his own food down in his room at mealtimes, he'll be less motivated to steal. The main thing is protecting Bjorn's routine and giving his gut a consistent, calm feeding environment. That combination — right food, separate rooms, no rushed eating — should make a real difference for him.
