Kitten vomiting after meals — best food fix

Vomiting within an hour of meals is a real red flag at 14 weeks — that's prime growth time and a kitten who can't keep food down simply isn't absorbing what they need. Kittens have very different nutritional requirements from adult cats: higher protein, more calories, and specific nutrients for bone, muscle, and immune development. Getting this phase right sets them up for life. Before I point you toward something better, a couple of quick questions: what food are you currently using, and is the vomiting every single meal or more occasional? Also, do you know if your kitten is a pedigree American Curl — some breeders provide early dietary notes that are worth knowing about.

That's almost certainly the problem. Supermarket own-brand dry kibble is often too high in cereal fillers and plant protein, and at 14 weeks a kitten's digestive system is still maturing — it really struggles with low-quality dry food, especially if she's bolting it down. The combination of hard kibble, poor digestibility, and a young gut is a classic recipe for post-meal vomiting. A few more things I want to know: is she vomiting undigested food or something more liquid? And is she otherwise bright, active, and gaining weight, or does she seem lethargic?

Undigested food with froth, hungry again immediately after — that's classic regurgitation rather than true vomiting, and it almost always points to the food being too hard to process or eaten too fast. The fact that she's small for her age confirms she's not absorbing enough nutrients even when she does eat. I'd move her off dry food entirely for now. What I'd recommend is Royal Canin Mother & Babycat Ultra Soft Mousse — it's a wet mousse specifically designed for kittens from birth to four months, with a very fine texture that's easy on an immature digestive tract, high-quality animal protein, and the exact nutrient profile a kitten this age needs. It's widely available on Amazon UK and it's what many breeders and vets reach for when a young kitten is struggling with dry food. The soft texture also slows the eating rate naturally, which helps with the regurgitation. Feed small portions four times a day rather than two larger meals and you should see a significant difference within a week.

Given that she's actively vomiting on the current food, I'd switch straight over rather than mixing — there's no benefit in continuing something that's clearly not working, and mixing wet food into poor-quality kibble doesn't improve the kibble. Go straight to the mousse from the next meal. If after two weeks she's settled and keeping everything down, you could introduce a small amount of Royal Canin Kitten dry biscuits on the side — but honestly, many cats thrive on wet food only and there's no nutritional reason to push kibble. Keep portions small and frequent for now: roughly four meals a day, about one to one-and-a-half pouches total across the day at her age and size.

Yes, I'd book a routine check-up rather than an emergency visit, but don't skip it. A vet can confirm there's no underlying issue — things like a hiatal hernia or pyloric stenosis are rare but worth ruling out in a kitten who's consistently sick after meals. They'll also weigh her properly and track whether she's on the right growth curve. If the food switch makes a clear improvement in the first few days, that's strong evidence it was dietary. But at 14 weeks, a vet who knows your kitten is always worth having on board regardless.
