Cat food for Siberian cats with chicken sensitivity

Siberians do have a notable tendency toward poultry sensitivity, so the vomiting after chicken-based food fits a familiar pattern. Digestive issues like this are usually food intolerance rather than a true allergy — the immune system isn't the problem, the ingredient just doesn't agree with them. Limited-ingredient or novel-protein diets tend to work well in these cases. To point you in the right direction: how long has the vomiting been happening, and is it shortly after eating or more random throughout the day?

That timing — within an hour, undigested food — is a strong sign of intolerance to something in that food, and chicken is the obvious suspect given her breed. The fact that she's otherwise healthy and a normal weight is reassuring; this is almost certainly dietary rather than something systemic. Has she ever eaten a food without poultry — duck, rabbit, fish, venison — and if so, did she tolerate it better?

Good to know — so we're starting fresh with a novel protein, which is actually ideal. You want something with a single clear protein source and no hidden poultry derivatives, which rules out a lot of mainstream foods. My recommendation is Lily's Kitchen Grain-Free Duck and Rabbit dry food. It uses duck and rabbit as the main proteins — no chicken, no turkey — with a short, clean ingredient list. It's genuinely limited-ingredient by design, not just by marketing claim, and it's one of the better options for cats with confirmed or suspected poultry sensitivity. The grain-free formulation also removes another common irritant. Start with a slow transition over 10–14 days to avoid upsetting her stomach further during the switch.

For the initial transition, I'd stick to one change at a time — switch the dry food first and give it three to four weeks. If the vomiting stops, you've found your answer. If you want to introduce wet food later, Lily's Kitchen also does wet recipes without poultry that would pair well. Changing both at once just makes it harder to know what's working if things improve or don't. Once she's settled on the new dry food, adding wet food is straightforward.

Good plan. Keep a note of how often she vomits in the first week on the old food so you have a baseline to compare against. Most cats with a simple protein intolerance improve clearly within two to three weeks once the offending ingredient is removed. If she's still vomiting at the same rate after a full month on the new food, that's worth a vet visit to rule out anything else — but based on what you've described, a clean protein switch is very likely to sort it.
