For how many days can I try to stimulate appetite before worrying?

It depends heavily on the species. A cat that eats nothing for more than a day or two is already a reason to call the vet, because of the risk of hepatic lipidosis. An adult dog tolerates a short fast a little better, but a total refusal beyond 24 hours, or with other symptoms, still needs assessing. In general: if it worsens, will not drink, or shows other signs, do not count the days, call straight away.

Can I add some human food to get it to eat?

With great caution, and not as a solution. Some human foods are toxic to dogs and cats, and others, given in quantity, unbalance the diet and cause the digestive upset that lowers appetite further. If you want to make the meal more appealing, better to warm the usual wet food or use a strong smelling food made for pets. If you have a specific addition in mind, ask the vet first whether it is safe.

My senior cat has eaten less for weeks: is that normal with age?

A slow decline in appetite in an older cat should not be waved away as simple old age. Behind it can be a dental problem, a kidney issue, a thyroid problem or more, all things that can be tackled once found. Palatability techniques help in the meantime, but they do not replace a check up: a senior eating less for weeks deserves a visit, even without immediate urgency.

Does it help to change brand or flavour often to find what it likes?

Constant changing usually makes things worse. Every abrupt change can cause digestive upset, and too much variety makes the animal even fussier. Better to work on how the same food is presented, temperature, smell and setting, before changing product. If a change is genuinely needed, do it gradually by mixing the new into the old over several days.

When an animal turns away from the bowl the temptation is a single one: push, hold the head to the food, keep it still and try to make it eat by force. It is nearly always the worst move. Forcing builds a negative link between the meal and being restrained, raises stress and often shuts down whatever appetite was left, especially in cats. A mild, passing dip in appetite, perhaps from heat, a small upset or a change of routine, is best handled by working on the levers that make food appealing: temperature, smell, texture and setting. This guide collects concrete techniques to reawaken interest without coercion, helps you see how much the animal is actually eating, and marks clearly the line beyond which do it yourself has to stop and the vet is needed.

First of all: is it appetite, or a symptom?

Not every refusal of food is a whim to fix with a few tricks. Sometimes loss of appetite is the tip of a health problem, and then stimulating appetite without tackling the cause is useless or harmful. Before you try any technique, pause and read the whole picture: how long it has not eaten, whether it drinks, whether it is bright or flat, whether there are other signs.

If it refuses water too, or drinks very little, this is no longer just an appetite problem.
If it is flat, vomiting, has diarrhoea, pain or trouble swallowing, the cause belongs to the vet before any appetite stimulation.
If it stopped suddenly and completely, that weighs more than a gradual, partial dip.
A senior animal eating less for weeks deserves a check anyway, even if it is not an emergency right now.

The levers that reawaken appetite

Appetite runs largely through smell, far more than through taste. Food that smells faint to us can be inviting or invisible to the animal depending on how we serve it. The main levers are four, and they act mostly on odour and on how easy it is to eat, not on piling in random calories.

The main palatability levers and how to use them. These are practical measures, not a cure: if the loss of appetite persists you need the vet.
Lever	What to do	Why it works
Temperature	Warm wet food to body temperature, never scalding	Heat releases the aromas and makes the smell stronger
Smell	Offer strong smelling food, wet or lightly moistened	Smell drives appetite more than taste does
Texture	Soften kibble with warm water or switch to wet food	Easier to eat for a sore mouth or a blocked nose
Setting	Bowl in a quiet spot, away from noise and other animals	Stress during the meal switches off appetite

A gentle protocol, step by step

The goal is not to get food in at any cost, but to recreate a setting in which the animal chooses to eat on its own. Move calmly, one step at a time, and give each attempt time to work before going on to the next. If a step makes things worse, step back.

Build calm around the bowl
Put the food in a quiet place, away from the litter tray, the noise and the other animals. Dim harsh lights and do not stare at the animal while it sniffs: close watching adds pressure.
Offer a little, and very appealing
A small amount of warm wet food is more inviting than a full, cold bowl. A modest portion that gets finished is worth more than a large one barely tasted and then left.
Stir the sense of smell with warmth and moisture
Warm the wet food slightly or moisten kibble with warm water. If needed, add a spoon of strong smelling food, as long as it suits the animal, to make the whole thing more inviting.
Try by hand, without forcing
Offer a little food on your palm or finger. The contact and the close up smell tempt many animals, but the gesture must stay an invitation: if it pulls back, do not insist.
Remove it and try again later
If after fifteen or twenty minutes it has not eaten, take the fresh food away rather than letting it dry out. Offer it again a couple of hours later: food left out and stale becomes part of the furniture and stops attracting.
Stop if warning signs appear
If the animal worsens, will not drink or refuses everything, stop the attempts and call the vet. Pushing past a certain point is not patience, it is delaying a visit that is needed.

Mistakes that switch off appetite

Many attempts to restart appetite achieve the opposite, because they bet on quantity and insistence instead of the setting. Recognising these mistakes is often more useful than any new trick.

Prising the mouth open or pushing the nose into the food: it builds fear of the meal and worsens the refusal.
Changing food every few hours: it confuses and can cause the digestive upset that lowers appetite further.
Filling the bowl: the sight of a mountain of food discourages more than it tempts.
Giving table scraps just to get something in: some are toxic and others unbalance the diet.
Using appetite stimulants or supplements on your own, without veterinary advice.

Measuring how much it really eats

The feeling that an animal is eating little is often imprecise. Weighing the food offered and what is left turns an impression into a figure, and that figure is exactly what the vet needs to judge whether the dip is mild or serious, and whether the techniques are working. Recording the trend also stops you from panicking too early or too late.

Weigh the portion before offering it and weigh what remains after each meal.
Note how much it eats at each meal, with the time and the type of food used.
Record whether and how much it drinks, because hydration counts as much as food.
Weigh the animal every few days on the same scale, to catch weight loss before it becomes obvious.
Bring this history to the visit: a curve of how much it ate says more than any spoken impression.

What to do next

Never force: coercion builds fear of the meal and shuts down what appetite is left. First rule out that it is a symptom, then work the palatability levers, warming wet food to body temperature and offering a little in a calm setting. Weigh what it eats and drinks to turn impression into data, and keep the sharp line in mind: in cats a refusal beyond a day or two, or any worsening, means the vet without waiting.
