Can Cats Eat Marmite?


As a cat owner, you may have wondered whether it’s safe for your feline friend to indulge in some of the foods you enjoy. Marmite, with its unique and divisive flavor, is a popular yeast extract spread among humans. However, when it comes to our cats, we need to consider their specific dietary needs and potential health risks. In this article, we’ll explore whether cats can eat Marmite and what effects it may have on their health.

What is Marmite?

Marmite is a savory yeast extract spread made from leftover brewer’s yeast. It is a rich source of vitamins, minerals, and amino acids, making it a popular choice among humans as a nutritious food spread. The distinct taste of Marmite has led to passionate debates, with some people loving its umami flavor, while others find it less appealing.

Understanding Cats’ Dietary Needs

Before considering introducing any new food to our cats, it’s crucial to understand their dietary requirements. Cats are obligate carnivores, meaning their diet must primarily consist of animal-based protein. They need specific nutrients, such as taurine, arachidonic acid, and vitamin A, which are essential for their overall health and well-being.

The Dangers of Onions and Garlic

Marmite contains trace amounts of onion and garlic derivatives, which can be harmful to cats. Both onions and garlic belong to the Allium family and can cause various health issues if ingested by cats. These issues include damage to red blood cells, leading to a condition called Heinz body anemia. Therefore, it is best to avoid feeding Marmite to your furry companion.

High Salt Content in Marmite

Another aspect to consider is the high salt content in Marmite. Cats have a lower tolerance for salt compared to humans. Excess salt intake can lead to dehydration, kidney problems, and other health complications in cats. Feeding Marmite to your cat can expose them to an unhealthy level of salt, which can be detrimental to their health.

Yeast Extract and Cats

Marmite is a yeast extract, and while small amounts may not be immediately harmful to cats, it does not provide the essential nutrients they need. Additionally, some cats may be allergic to yeast, which can lead to skin irritations, digestive issues, or respiratory problems. To ensure your cat’s health and safety, it’s best to stick to a balanced diet formulated specifically for feline needs.

Potential Gastrointestinal Upsets

Introducing new foods, especially those with strong flavors like Marmite, can upset a cat’s sensitive stomach. Cats have delicate digestive systems, and abrupt changes to their diet can result in diarrhea, vomiting, or loss of appetite. To avoid any gastrointestinal issues, it’s advisable to steer clear of feeding Marmite to your cat.

Consulting a Veterinarian

If you are ever uncertain about whether a particular human food is safe for your cat, it’s essential to consult your veterinarian. Veterinarians can offer personalized advice based on your cat’s individual health and dietary requirements. They can guide you on the best choices for treats and ensure your cat’s well-being remains a top priority.


In conclusion, cats should not consume Marmite or any other human food outside of their specialized diet. While Marmite is a nutritious choice for humans, it lacks the essential nutrients that cats require to stay healthy. Moreover, ingredients like onions, garlic, and high salt content pose potential risks to feline health. Always prioritize your cat’s well-being by providing them with a balanced, cat-specific diet.
