What is custard?

Custard, a British dessert, is a thick and creamy mixture of milk, eggs, and sugar that can be used in a variety of ways.

Depending on the recipe, you may need to heat the ingredients until they thicken or cook the eggs until they are set. Vanilla or other flavors like cocoa powder or almond extract may be added to some forms of custard. Custard can be eaten both warm and cold.

Ingredients used in making custard and how they affect your cat


Salt is used as a preservative in both human and animal food. It is an ingredient in many human foods, including powdered custard. However, cats do not have a salt tolerance and should not consume large amounts of salt.

An electrolyte imbalance and dehydration in cats is a common problem caused by salt. In addition, it can cause life-threatening health issues like kidney failure, heart disease, and even death. There is a daily salt intake limit of 1.25g/kg for cats.

If you must feed your cat food with salt, limit the amount and keep a close eye on your feline friend for any adverse reactions. Reduce the amount of salt in your cat’s food and take him to the vet if you notice that he is constantly drinking water or losing weight.


Too much sugar is bad for humans, but did you know it can also be harmful to your cat? Excessive sugar consumption can cause obesity and diabetes in cats, just as it can in humans.

Because of how frequently it begs for a taste of our sugary foods, you might think your cat has a sweet tooth. It’s important to be aware of the dangers of sugar because cats can’t taste it and don’t metabolize it the same way we do.

Your cat probably won’t get sick from eating a small amount of sugar, but there are risks associated with giving them too much. The risks of giving cats too much sugar are as follows:

Like humans, cats can become overweight from eating too much sugar. Sugar causes fat accumulation in a cat’s body. Diabetes, joint pain, and cardiovascular disease are just some of the issues that can arise from being overweight.

One of the gravest threats that sugar poses to cats is diabetes. When felines consume an excessive amount of sugar, insulin production increases. Diabetes can develop from this over time. Diabetes in cats causes them to lose weight, drink more water, and urinate more frequently.

Cats can get tooth decay from sugar just like humans can. Bacteria thrive in the sugary film that forms on your cat’s teeth. Cavities and gum disease can result from this.

There are numerous reports of animals becoming fatally ill after consuming milk on the internet. Even “clean” milk can be dangerous for cats. Usually the milk is contaminated with bacteria or other toxins.

Obligate carnivores like cats can only properly absorb the proteins found in animal flesh. Milk provides cats with some of the calories and fat they need, but it does not provide the high-quality protein they require.

Also, lactose, a sugar found in milk, is difficult for many cats to digest. Not being able to digest lactose properly can lead to nausea, vomiting, and diarrhea.

So, what’s the conclusion, if any? Cats don’t need milk, and in fact, it’s not good for them. Choose a low-lactose milk or don’t give it to your cat at all if you must.

Artificial colorings, flavoring, and preservatives

Did you know that many of the additives used in cat food and treats are artificial and can have a negative impact on your cat’s health? This is why you need to read the labels of the cat food you buy to make sure there are no questionable ingredients.

Cats should avoid eating anything flavored with artificial ingredients, even if it tastes better to us. MSG, which is found in many artificial flavorings, has been linked to neurological problems in felines, including vomiting, dizziness, and even seizures.

Cats should avoid eating food and treats that have been preserved with artificial preservatives. Numerous studies have shown that artificial preservatives like BHA and BHT can cause cancer in humans.

Try to find cat food and treats that are made from all-natural ingredients and don’t have any artificial ingredients.

The protein and fat content of this diet is high, while the carbohydrate content is low.

While it’s true that cats thrive on a diet high in animal protein and fat, eating too much of either can be dangerous. Obesity is caused by too much fat in cats just as it is in humans. Cats can develop diabetes, joint pain, and breathing problems due to their excess weight.
