Who doesn’t love a good custard? The sweet, creamy goodness is hard to resist, especially when paired with your favorite dessert. But as a cat owner, you may be wondering if it’s safe for your feline friend to indulge in the same treat. So, is it OK for cats to eat custard? Well, the answer isn’t as simple as a yes or no.

Cats are known for being picky eaters, but they can also be quite curious and adventurous when it comes to trying new foods. However, not all human foods are safe for cats and some can even be toxic. Custard, made with milk, sugar, and eggs, isn’t necessarily dangerous for cats but there are some health risks that pet owners should be aware of.

In this blog post, we’ll explore the potential benefits and drawbacks of feeding custard to cats. We’ll also answer some commonly asked questions about this topic and provide tips on how to safely incorporate human food into your cat’s diet. Plus, we’ll discuss some cat-friendly alternatives to custard that will satisfy their sweet tooth without putting their health at risk.

So, sit back and relax. Let’s dive into the delicious world of feline nutrition together.

Cats as Obligate Carnivores

Unlike humans, they require a diet that is high in animal-based protein to maintain optimal health. This means that their bodies need certain amino acids, vitamins, and minerals that can only be found in meat. As a result, feeding them foods that are high in carbohydrates or sugars, such as custard, can lead to significant health issues.

For starters, cats lack the necessary enzymes to digest carbohydrates effectively. Consuming foods that are high in carbohydrates can cause a range of health problems, including obesity, diabetes, and digestive problems. Additionally, custard contains high amounts of sugar and carbohydrates, which can lead to weight gain and other health issues.

Furthermore, some custard recipes include added sugars and xylitol which are toxic to cats. Even small amounts of xylitol can cause rapid insulin release, leading to hypoglycemia (low blood sugar) and liver failure. Additionally, some cats may have a lactose intolerance which means they cannot digest lactose properly. Consuming dairy products such as custard can lead to diarrhea and other gastrointestinal issues.

As a responsible pet owner, it’s crucial to provide your cat with the right diet that meets their nutritional needs. Foods that are high in animal-based protein and low in sugars and carbohydrates are ideal for cats. Cooked meat or cat-friendly treats designed for their dietary needs make excellent options for treats. Feeding your cat a balanced diet ensures they maintain optimal health.

Potential Health Risks of Eating Custard

While it may be tempting to give them a taste of your custard, it’s important to consider the potential health risks first.

One of the main concerns with feeding custard to cats is its high sugar content. Just like humans, cats can suffer from obesity and dental problems if they consume too much sugar. A healthy diet is crucial for your cat’s overall well-being, so it’s best to avoid feeding them sugary treats like custard.

Dairy products such as milk and cream are also commonly found in custard. However, many cats are lactose intolerant and cannot properly digest lactose. Consuming lactose can lead to digestive issues like bloating, diarrhea, and vomiting, which can quickly lead to dehydration. It’s important to note that dehydration can be life-threatening for cats, making it crucial to avoid foods that can cause such issues.

Furthermore, some types of custard may contain xylitol, a sugar substitute that is toxic to cats. Even small amounts of xylitol can cause liver failure and seizures, which could be fatal for your feline friend.

Lastly, custards often contain additives like artificial flavors, colors, and preservatives that can be harmful to cats with sensitive digestive systems or allergies.

Added Sugars and Flavorings in Custard

While custard may be a delicious treat for us humans, it can be harmful to cats, especially when it contains added sugars and flavorings.

Cats are obligate carnivores, meaning their bodies are not designed to digest large amounts of carbohydrates or sugars. Consuming too much sugar can lead to obesity, diabetes, dental problems, and other health issues in cats. This is why added sugars such as corn syrup, high fructose corn syrup, and sucrose, which are commonly used to enhance the taste of custard, can be harmful to our furry friends.

But it’s not just added sugars that we need to be cautious about. Flavorings such as vanilla extract or other artificial flavors may also be added to custard. While these flavorings may not necessarily be harmful to cats, they don’t provide any nutritional value either. In fact, some artificial flavors may contain chemicals that can be harmful to cats if consumed in large quantities.

So what can you do to keep your furry friend safe? Always read the ingredient labels on any custard products you plan on giving your cat. Opt for plain custard made with natural ingredients such as milk and eggs. This ensures that your cat receives a balanced diet that meets their unique nutritional needs without exposing them to unnecessary risks.

The Dangers of Xylitol for Cats

It’s crucial to be aware of the potential dangers of xylitol for cats.

Xylitol is a sugar substitute commonly found in sugar-free products such as gum, candy, and baked goods. While it may be safe for humans, it can be extremely harmful to cats. When ingested, xylitol can cause a rapid release of insulin in cats, leading to hypoglycemia or low blood sugar. This can result in symptoms such as vomiting, loss of coordination, seizures, and even liver failure.

To keep your cat safe, it’s important to always check the labels of any food items before feeding them to your feline friend. Custard, for example, may contain xylitol as a sweetener. Even if the custard does not contain xylitol, it’s still not recommended to give your cat any kind of dessert or sugary treat.

If you suspect that your cat has consumed xylitol or any other toxic substance, seek veterinary care immediately. Delaying treatment can lead to serious health complications or even death. It’s also important to keep human food out of reach of your cat and stick to a balanced diet recommended by your veterinarian.

Lactose Intolerance in Cats

It’s important to keep in mind that not all treats are created equal. In fact, some treats can be harmful to cats with lactose intolerance, a common condition that affects their ability to digest lactose, a sugar found in milk and other dairy products.

Lactose intolerance in cats occurs when their bodies stop producing lactase, the enzyme that breaks down lactose. This leads to a buildup of undigested lactose in the digestive system, which can cause a range of uncomfortable symptoms such as diarrhea, vomiting, and abdominal pain. Unfortunately, custard is made from milk and other dairy products, making it problematic for cats with lactose intolerance.

To ensure your cat’s health and wellbeing, it’s crucial to be aware of their health conditions and dietary needs before feeding them any human food, including custard. Instead of offering them custard, cat owners should prioritize their cat’s nutrition by providing a balanced and appropriate diet that meets their specific dietary needs.

If your cat does have lactose intolerance, they may benefit from a diet that is low in lactose or completely free of dairy products. Luckily, there are many cat food options available on the market that are formulated specifically for cats with sensitive stomachs or dietary restrictions. To make sure you’re making the right choices for your furry friend, it’s always best to consult with a veterinarian before making any significant changes to your cat’s diet or feeding them any human food.

Nutritional Needs of Cats

Unlike dogs, cats are obligate carnivores, which means that their diet needs to be high in animal protein. This is because cats are unable to synthesize certain essential amino acids, such as taurine and arginine, which are found primarily in animal tissues.

But protein is not the only thing that cats need in their diet. They also require specific vitamins and minerals to ensure they get a balanced meal. For instance, vitamin A is vital for maintaining healthy vision and skin, vitamin D helps regulate calcium levels in the body, and vitamin E acts as an antioxidant to protect cells from damage.

In terms of minerals, calcium and phosphorus are essential for bone health, while potassium is necessary for proper muscle function. Cats also need trace minerals like iron, copper, and zinc in small amounts.

It’s important to note that cats have a low thirst drive and may not drink enough water on their own. Therefore, it’s crucial to provide them with moist food or access to fresh water at all times to prevent dehydration.

When looking for cat food, consider purchasing high-quality brands that meet your cat’s nutritional needs. Avoid feeding them human food like custard or other treats that lack the necessary nutrients they require.

Alternatives to Custard for Cats

Their digestive system is designed to process meat-based protein rather than carbohydrates found in custard. Consuming custard can cause digestive issues such as diarrhea, vomiting, and even pancreatitis in cats. But don’t worry, there are numerous alternatives that can provide your cat with a safe and enjoyable treat.

First on the list of alternatives to custard for cats are plain yogurt or cottage cheese. These dairy products are lower in lactose than custard and can provide some nutritional benefits such as calcium and protein. However, it’s essential to note that you should only offer your cat small amounts of these treats occasionally.

Canned pumpkin is another alternative that can be an excellent addition to your cat’s diet. This low-calorie vegetable is high in fiber and can help regulate your cat’s digestive system. You can mix a small amount of canned pumpkin with your cat’s regular food or offer it as a treat.

If you’re looking for a sweet treat for your furry friend, fresh fruit like blueberries, strawberries, or sliced bananas can be a great alternative to custard. However, remember that fruit should only make up a small portion of your cat’s diet and should be given in moderation.


In conclusion, while we may be tempted to share our delicious custard with our feline friends, it’s best to avoid doing so. Cats are obligate carnivores and require a diet that is high in protein and low in carbohydrates and sugars. Foods like custard, which are high in carbs and sugar, can lead to significant health issues for cats.

Custard is packed with sugar and carbs, which can cause weight gain, diabetes, and other health problems in cats. Moreover, some types of custard contain xylitol or added sugars and flavorings that can be harmful to cats with sensitive digestive systems or allergies. The dairy products found in custard can also cause digestive issues such as bloating, diarrhea, and vomiting.

To keep your furry friend healthy and happy, it’s crucial to provide them with a balanced diet that meets their specific dietary needs. Instead of giving them sugary human treats like custard, opt for cat-friendly treats or cooked meat.

If you’re looking for alternatives to custard for your cat’s occasional treat time, consider plain yogurt or cottage cheese in small amounts. Canned pumpkin is an excellent addition to their diet as it is low in calories but high in fiber. Fresh fruits like blueberries or sliced bananas can also make a sweet treat but should only make up a small portion of their diet.

Remember always to check the ingredient labels on any food items before feeding them to your feline friend and consult with your veterinarian before making any significant changes to their diet.
