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.

A greasy coat showing up after starting a fish-based food is actually a really useful signal — it tells you the fat profile isn't agreeing with your kitten's skin. Before I point you toward a poultry option, I want to make sure I get this right for your Munchkin specifically. How old are they exactly, and how long have you been noticing the coat change? Also, are they eating wet food, dry, or a mix?
She's just turned 6 months. The greasiness started maybe 3 or 4 weeks after I switched her onto a salmon-based wet food. She's been on that exclusively since then. She's a purebred Munchkin — short legs, solid little build.

That timeline is really helpful — 3 to 4 weeks in is about when a coat reaction like this tends to show up. Munchkins don't have any specific dietary quirks, but they do tend to carry weight easily, so the fat content in her food matters more than it might for a leaner breed. High-fat fish oils are brilliant for some cats but can absolutely tip certain kittens into greasy skin territory, especially if the omega-6 to omega-3 ratio is off. Moving to poultry is a sensible instinct. Can I ask — is she indoor-only, and has she been spayed yet? That affects how calorie-dense her food should be.
She's fully indoor and not spayed yet — that's booked for a couple of months' time. She's quite active indoors though, always tearing around.

Perfect — that's exactly what I needed. Given she's 6 months, unspayed, active, and a Munchkin build, I'd go with Royal Canin Kitten dry food as your main recommendation. It's chicken-based, so it sidesteps the oily fish issue entirely, and it's specifically formulated for kittens up to 12 months with the right protein and calcium levels for bone development — which matters for Munchkins given the cartilage variation in their legs. The kibble size is also designed for young cats, so it's easy for her to manage. I'd phase in the switch over about 7 days to avoid any stomach upset, mixing it gradually with what she's currently on. Once she's spayed, keep an eye on portions — Munchkins can gain weight quickly after neutering — but Royal Canin does a Kitten Sterilised version you can move her onto at that point.
That makes a lot of sense. Should I drop the wet food completely or keep some alongside the dry?

I'd keep a small amount of wet food in the mix — it's a good way to keep her hydration up, which matters more for indoor cats than people realise. If you want to stick with the poultry theme, look for a chicken or turkey-based wet food without added fish oils listed in the ingredients. A rough split of 70% dry to 30% wet works well at this age. The key thing is that the dry Royal Canin Kitten becomes the base of her diet, since that's where the nutritional balance is dialled in. You should start seeing improvement in the coat within 4 to 6 weeks of the switch being complete.
Brilliant, thank you. I'll order it today and start the transition this week.

Great — you're doing exactly the right thing catching this early. A greasy coat at 6 months is worth taking seriously and you've got a straightforward fix. If the coat hasn't settled within 6 weeks of the full switch, it's worth a vet check just to rule out anything else going on, but in my experience a fish-to-poultry switch resolves it in the majority of cases. Good luck with her — Munchkins are brilliant little characters.
