This is a specific conversation about Kitten food — the right nutrition from the start — ask about yours and get one honest answer for your exact situation.

Grain-inclusive kibble causing excessive gas in a Siberian kitten is actually a really common pattern — Siberians tend to have sensitive digestive systems, and many simply don't tolerate the grain fillers well at all. Kittens have very different nutritional needs from adult cats — they need higher protein, more calories, and specific nutrients for bone and muscle development — so getting this phase right really does set them up for life. A few quick questions before I point you in the right direction: how old is your kitten exactly, do you know the breed lineage or is it a pure Siberian, and what grain-inclusive food were they on when the gas started?
She's 5 months old, pure Siberian from a breeder. She was on Royal Canin Kitten and the gas was pretty bad — I've already switched to a grain-free dry food but it's still not great. Not sure if I picked the right one.

Good that you've already moved away from the Royal Canin — that formula is quite high in rice and corn, which can absolutely be the culprit. Can I ask which grain-free you've switched to, and roughly how long she's been on it? Also, is the gas the only symptom, or are you seeing any soft stools or bloating alongside it?
She's been on Applaws Kitten dry for about three weeks. The gas is better than before but still there, and her stools are a bit inconsistent — sometimes fine, sometimes loose.

Three weeks is enough time to see a meaningful response, and the fact that it's only partially improved tells me something. Applaws is decent but it's relatively low in overall protein and fat for a growing kitten, and it uses quite a lot of chicken meal as the primary protein source. For a Siberian at this age, I'd want to see a food that's much more meat-dense, with a wider protein variety and no starchy fillers at all. The loose stools alongside the gas suggest her gut flora is still struggling to stabilise — that points to needing a cleaner, richer diet rather than just grain-free for its own sake.
That makes sense. So what would you actually recommend for her?

I'd go with Orijen Cat & Kitten dry food. It's genuinely one of the most meat-dense kibbles available in the UK — around 90% animal ingredients, with fresh or raw chicken, turkey, flounder, and eggs all featuring prominently. There are no potatoes, no legume fillers, and no grains — but crucially it also avoids the heavy pea and lentil loading that some grain-free foods use as a replacement carb. For a Siberian kitten still developing muscle and bone, the protein level and amino acid profile here are excellent. The fat content is also high enough to support her energy needs at five months. Most owners with gassy or sensitive kittens see a real difference within two to three weeks of settling in. Transition her slowly over about ten days — mix it in gradually — because jumping straight in on a richer food can temporarily worsen loose stools. You'll find it on Amazon UK, usually in 1.8kg or 5.4kg bags.
Brilliant, that sounds exactly like what I was looking for. I'll order the small bag first to trial it. Should I add anything else, like a probiotic?
inparticular.ai
Starting with the small bag is the right call. On the probiotic question — yes, honestly it's worth it during the transition. A short course of a feline-specific probiotic like Pro-Kolin Enterogenic or even a simple paste like Protexin Pro-Kolin can help stabilise her gut flora while she adjusts to the richer food. It doesn't need to be permanent — four to six weeks around the transition period is usually enough. After that, if the Orijen is agreeing with her, her digestion should self-regulate. Watch the stool quality as your main guide: if it firms up and the gas settles, you've found your answer.
