When a cat who has been eating raw food well suddenly—or gradually—begins to reject meals, the most likely cause, assuming an underlying medical condition can be ruled out, is the meat.

Rule Out Medical Causes First

That said, the first step should always be to consider health. Several medical issues can lead to inappetence or food refusal in cats. Some are relatively minor, such as temporary gastric upset or constipation. Dental pain can also reduce appetite, although many cats will still eat despite oral discomfort.

More persistent issues such as chronic gastritis or gastroenteritis often cause a notable reluctance to eat, sometimes accompanied by vomiting (often of hairballs) or diarrhoea. These cases can be difficult to pinpoint and resolve. However, it is systemic disease that most significantly affects appetite. Any gradual decline in interest in food should prompt investigation. Conditions such as sub-clinical infections, hyperthyroidism, kidney disease, and disorders of the liver, heart, or pancreas can cause nausea, dizziness, or general malaise—making food seem unappealing. In these cases, a cat may still eat small amounts of highly novel or rare foods, such as cooked chicken, plain liver, dry food, or a bit of cream, but not their usual meals.

When the Meat is the Problem

If illness can be ruled out and the cat has otherwise thrived on raw food, the issue almost always lies with the meat.

That realisation can bring relief, but it also presents a new challenge. Understanding what has changed in the meat—and how cats perceive it—is not straightforward. Cats have an extraordinarily refined sense of smell and taste, capable of detecting chemical changes that are entirely imperceptible to us. Even slight oxidation of fats, enzymatic degradation, bacterial by-products, or changes in flavour due to what the meat animal ate, its health status, or the materials the meat came into contact with (such as plastic wrap or disinfectant washes) can cause a cat to reject it.

Unlike some animals, cats are unlikely to eat food they find objectionable simply because they are hungry. This isn’t stubbornness—it’s a survival trait. As obligate carnivores, they have little tolerance for spoiled food, and their selective eating habits have likely helped them avoid illness in the wild. Unfortunately, this same caution can make feeding difficult when something seems “off” about the food—even if we can’t detect it. A higher fat content alone–which can change food aroma and mouth feel–may be off-putting to many cats.

Early Life Experience Shapes Attitudes to Food

A cat’s relationship with food is largely shaped between 4 and 10 weeks of age, during the transition from milk to solid food. Kittens who experience any degree of food insecurity during this time often develop a lifelong drive to eat. These cats tend to be extremely food motivated, rarely refuse food, and adapt easily to dietary changes. They may have started life as strays, ferals, or in overcrowded or neglected environments. While they can be challenging to live with—helping themselves to anything left unattended—they are typically very easy to feed raw and continue eating even when unwell.

Conversely, kittens raised in more stable conditions, with food available around the clock, usually develop a more measured relationship with eating. They are less likely to scavenge and more likely to leave food they don’t enjoy. These cats often require gradual transitions when introducing new foods and may respond to illness, even mild, with a complete loss of appetite. In particular, cats who were weaned directly onto dry food with free access may appear to treat eating as optional. For caregivers, this can be deeply stressful.

Meat is not Consistently the Same

Even when a cat has reliably eaten a particular type of meat for months or years, that doesn’t mean that the next pack of the same meat is equally well received. This applies to all meats. There is no guarantee that a new batch will be accepted, even when labelled the same. Differences in fat content, freshness, storage, animal diet, and processing can affect aroma and taste—often in ways we cannot detect.

To reduce the chances of rejection due to subtle changes, it is helpful to:

• Choose the freshest, extra lean meats available
• Check packaging dates, and avoid meats wrapped in cling film
• Keep meat cold during transport, refrigerate it promptly, and prepare the food the same day
• Freeze completed meals immediately after preparation

Factors Outside Our Control

Unfortunately, some variables are outside the consumer’s control—such as whether the meat animal was male or female (which can affect taste), its health, or whether the packaging materials transferred undesirable flavours. Many meats, particularly poultry, are washed in chlorinated water, which may affect flavour. Plastic wrap can leach volatile compounds into the meat, resulting in a taste that some cats find objectionable.

Buying in Bulk for Consistency

One effective strategy is to buy a larger quantity of meat in a single batch—enough for several months or even a year—portion it into 450g packs and freeze it immediately. A 32 kg supply is usually sufficient for one cat for a year. Meat sourced directly from a farm, specialty butcher, meat market, or meat wholesaler can be of higher quality because it is less handled. Many farms and wholesale suppliers now offer online sales. It is wise, however, to speak with the supplier beforehand to explain your needs, and if possible, visit in person to see what kind of business they run.

When Re-transitioning is Needed

If buying bulk is not an option, switching to another meat type should be tried, or it may be necessary to re-transition gradually. Sometimes simply mixing in a small amount of a favourite wet food or something highly palatable, such as canned salmon, can encourage acceptance. Food toppers such as nutritional yeast flakes, freeze-dried liver powder, or pulverised dry cat food are also often effective. They can be used long-term if needed. Warming the food slightly—just 10 seconds in the microwave—can help by enhancing aroma and softening cold textures. Most cats have cold-sensitive teeth.

In Summary

• Rule out illness first. Your cat may have a simple stomach upset that is resolved by the next day. However, changes in appetite could be early signs of a serious chronic condition.
• If illness is not the cause, focus on the meat. Even familiar meats can vary in ways that matter to your cat.
• Buy the freshest, extra lean meats available. Check for recent packaging dates and avoid cling wrap.
• Keep meat cold and prepare food the same day. Freeze finished food immediately.
• Consider bulk-buying from a trusted supplier. A single batch reduces variability and may offer better quality.
• If needed, reintroduce raw food gradually. Mix with familiar favourites or top with palatable additions.
• Warm food gently before serving. This can improve aroma and texture, and make meals more appealing and comfortable to eat.
• Use food toppers to increase acceptance. Nutritional yeast, liver powder, or pulverized dry food can often help.
