Cat food for Burmilla sensitive stomach

Burmillas are genuinely prone to protein sensitivities, so vomiting undigested food in a five-year-old of the breed is a fairly clear signal that something in the current diet isn't agreeing with them. Digestive issues like this are usually food intolerance rather than true allergy, and limited-ingredient or novel-protein foods tend to resolve it where other changes don't. To point you in the right direction — are the vomiting episodes happening shortly after eating, how long has this been going on, and what are you currently feeding?

That timing — undigested food within 20 minutes — points strongly to a protein intolerance rather than a lower-gut issue. Chicken is one of the most common culprits in cats with sensitivities, and Burmillas in particular seem to react to it more than other breeds do. Two years on the same food is also long enough for an intolerance to develop even if it wasn't a problem initially. Has she had any other symptoms alongside the vomiting — loose stools, weight loss, or changes in coat condition?

The dull coat and reduced appetite fit the picture — chronic low-level intolerance often shows up that way. The absence of loose stools is useful too; it suggests this is happening at the stomach rather than further down, which makes a protein switch very likely to help. I'd move her away from chicken entirely and onto a novel protein she hasn't been exposed to. My recommendation is Lily's Kitchen Fabulous Fish dry food for cats. It's a single-protein, fish-based recipe with a short, recognisable ingredient list — no chicken, no common fillers — and it's well-suited to sensitive cats where the trigger is a common poultry protein. The quality of the ingredients also tends to show quickly in coat condition. Switch gradually over about ten days to avoid any transition upset, and you should have a clear picture within three to four weeks of whether the vomiting resolves.

Dry food is fine as a main diet as long as she's drinking reasonably well, which most cats do when they're otherwise healthy. That said, if she's reluctant to eat or the vomiting persists after the protein switch, moving to wet food is worth trying — it's easier on the stomach and the higher moisture content can help with digestion. For now I'd try the Lily's Kitchen Fabulous Fish dry first, since minimising too many changes at once makes it easier to see what's actually working.

Good luck with her — a straightforward protein swap like this often makes a noticeable difference quite quickly. If the vomiting hasn't improved after four weeks on the new food, it's worth a vet visit to rule out anything structural, but my bet is the chicken was the issue all along.
