Cats vomit for many different reasons, and most cases are neither alarming nor unusual. Hairballs, food swallowed too quickly, an abrupt change in diet or a stomach reacting to something unfamiliar are among the most common explanations for why cats vomit. What matters is not whether it happens a single time, but whether it becomes a pattern and whether your cat is otherwise thriving. Below we go through the most common causes, how you can tell vomiting apart from ordinary regurgitation, and when it is time to contact your vet.

Hairballs: the most common explanation for vomiting in cats

Cats are meticulous about their coat and spend a large part of the day grooming themselves. When they lick themselves, loose hairs go down into the stomach, and some of it passes quite naturally through digestion. But some of it collects, and when the stomach wants to get rid of it, it comes back up as a hairball - often elongated and shaped by the oesophagus. This is typically accompanied by a characteristic coughing or moaning just beforehand.

Hairballs occur more often in long-haired cats and during periods of heavy shedding in spring and autumn. Regular brushing removes loose hairs before your cat gets a chance to lick them in, thereby reducing the amount of fur that ends up in the stomach. A diet with a sensible fibre content and good digestibility also supports the hairs passing naturally through the system rather than accumulating.

Does your cat eat too fast or too much at a time?

A cat that vomits its food up largely uneaten shortly after the meal has usually eaten too quickly. Some cats swallow their meal in large mouthfuls without chewing, and the stomach reacts by sending it all back up. This is seen especially in multi-cat households, where competition for the bowl makes them eat in a hurry, and in cats that are only fed once or twice a day and are therefore very hungry when the food finally arrives.

The solution is often simple. Divide the daily ration into several smaller meals so that your cat does not empty a full bowl all at once. If you feed several cats, it can help to give them each their own bowl with distance between them, so the meal becomes calmer. Meals with small pieces of an appropriate size also make it easier for the cat to eat at a more relaxed pace. In Cat Meals you will find meals composed for the cat's natural needs, where taste, nutritional profile and bite size work together.

Can a change of food make the cat vomit?

A cat's digestion is a creature of habit. If you switch abruptly from one meal to another, the stomach may react with vomiting, loose stools or lack of appetite while it gets used to the new ingredients. This is rarely a sign that the new food does not suit the cat - it is most often because the transition happened too quickly.

A gentle change of food over about a week gives the stomach time to adapt. Start by mixing a small amount of the new meal into the familiar one and gradually increase the proportion day by day until the cat is fully switched to the new one. If you are unsure how best to plan the transition for your particular cat, you can contact ESSENTIAL FOODS' nutrition advisors, who are ready by phone, chat and email to advise on feeding, food and nutrition.

Sensitive stomach and reactions to certain ingredients

Some cats have a more sensitive digestion than others and react to certain ingredients or to food of fluctuating quality. Here it is about finding meals composed of carefully selected ingredients with high digestibility, so the stomach is burdened as little as possible. A stable, well-prepared diet with a sensible content of animal ingredients is close to the cat's natural needs as a carnivore and is often gentle on a delicate stomach.

ESSENTIAL FOODS' cat meals are prepared from human-grade ingredients and fresh raw materials, and because the cat is a distinct carnivore, the meals place great emphasis on animal content. A grain-free profile can be relevant if your cat has allergies or special dietary needs, and you can find the grain-free meals gathered in the collection Grain-Free. Be aware that grain-free does not in itself mean a high proportion of animal ingredients - it is the composition of the individual meal that determines this.

Is it vomiting or regurgitation? How to tell the difference

It is worth distinguishing between vomiting and regurgitation, because the two things mean something different. With vomiting, the stomach contracts and the cat coughs or moans before the contents come up - it is an active process, and what comes out is often partly digested. Regurgitation, on the other hand, happens without effort. Here the food runs up from the oesophagus shortly after it has been swallowed, and it is typically uneaten and shaped like a sausage. Regurgitation is most often linked to eating too fast or portions that are too large.

This distinction is useful when you talk to your vet, because it tells something about where in the system the problem arises. Note when it happens in relation to the meal, how often it recurs, and what it looks like. These observations are valuable if the pattern continues.

When should you contact the vet?

A single instance of vomiting in a cat that is otherwise happy, eats normally and behaves as usual is rarely cause for concern. The picture changes if the vomiting recurs over several days, becomes frequent, or if it is accompanied by other changes in your cat's condition. If vomiting is combined with lethargy, lack of appetite, altered behaviour or weight loss, you should contact your vet, who can examine the cat thoroughly and find the underlying cause.

As the cat's family, you know it better than anyone else, and your sense that something is different is worth listening to. ESSENTIAL FOODS' nutrition advisors can help you with questions about feeding, food and nutrition, but they never replace the vet. For any health concern, the vet is the right one to turn to.

How to support a calm stomach in everyday life

Much of what prevents vomiting lies in the daily routines. Fixed feeding times, portions divided across the day and a calm place to eat make the meal more balanced and reduce the risk of the food coming back up. Fresh water available at all times and regular brushing during shedding periods further help keep both digestion and coat in balance.

The foundation, however, is always the food itself. Meals prepared from exquisite ingredients with a nutritional profile that matches the cat's nature as a carnivore give the stomach the best conditions for functioning stably day after day. You will find the entire range under Cat Food, where the meals are composed with the cat's wellbeing in mind - from kitten to the golden years. If your cat is going to try something new before you decide, you can start with one of the smaller Trial Meals for Cats, so the stomach gets a gentle introduction and you can see what your cat prefers to eat.

In most cases, cats vomiting is a completely natural part of living with a cat, and most often the cause is trivial and temporary. By keeping an eye on how often it happens, what it looks like, and how your cat is otherwise doing, you get a good basis for assessing whether it is simply a hairball or a meal eaten too fast - or whether it is time to call the vet. With fixed routines, calm meals and a high-quality diet, you give your cat's stomach the best conditions for feeling good.
