We’ll discuss mayonnaise’s ingredients, nutritional value, and why your cat shouldn’t eat it in this comprehensive guide. Understanding the reasons for this restriction will help you feed your cat a safe, healthy diet without mayonnaise.

What Is Mayo?
Mayonnaise, or “mayo,” is a creamy condiment that cats should not eat. Cats are obligate carnivores, meaning their bodies are built to eat animal proteins.
Humans invented mayo. It may have been invented in 18th-century Mahón, Menorca, Spain.
Mayo has egg yolks, oil, vinegar or lemon juice, and seasonings.
It can add flavor and creaminess to human dishes, but cats should never eat it because it lacks essential nutrients. Always feed your cat a diet that meets their nutritional needs and consult a vet for advice.
Is Mayo Bad for Your Cat?
To determine if mayo is safe for your cat, look closely at what’s in it. Here is a list of the common ingredients in mayonnaise and what they mean for cats’ health:
Soybean Oil:
Soybean oil, Mayo’s main ingredient, worries cats. High fat can upset your cat’s stomach, causing diarrhea and vomiting. Mayo’s high caloric density can cause cat obesity, leading to heart, kidney, and liver disease.
Obesity strains your cat’s joints, mobility, and body temperature regulation. Avoid foods that cause weight gain because overweight cats may have trouble grooming.
Eggs:
Cats can eat small amounts of eggs, which are found in mayonnaise. Egg yolks, on the other hand, are high in fat and cholesterol, which can make cats fat.
Overeating cholesterol can also cause pancreatitis, heart disease, and hyperlipidemia, marked by seizures, rough skin, and issues with the nervous system.
Vinegar and Lemon Juice:
Small amounts of vinegar and lemon juice are in mayonnaise. While vinegar can repel cats, mayo is unlikely to be eaten by a cat that detects it.
However, limonene in lemon juice can cause diarrhea, vomiting, depression, liver failure, tremors, low blood pressure, and even death in cats. Thus, even trace amounts of lemon juice in mayo should be avoided.
Salt:
A lot of store-bought mayonnaise has salt in it. Cats can handle more salt than people, but too much sodium can dehydrate cats, give some cats heart problems, and cause them to hold on to water.
If your cat overeats salt, it may drink more water, making them use the litter box more often.
Sugar:
Many commercial mayos contain sugar. Sugar isn’t toxic to cats but can cause weight gain by providing empty calories.
It may also increase hyperglycemia in older cats and dental disease, a familiar cat issue. Cats with diabetes should avoid sugar because they have trouble processing it and can’t taste it.
Mustard:
Some brands of mayonnaise contain mustard, which isn’t poisonous to cats by itself, but the preservatives and other ingredients in mustard can make some cats allergic. Because of this, you should be careful when giving your cat mayo with mustard.
The base mixture of mayo is already not good for cats, but other things also need to be considered.
Some kinds of mayo are made without eggs for vegans or people allergic to eggs. This takes out the one ingredient that cats can safely eat.
Also, many different kinds of mayo have other things that are bad for cats, like sugar and salt.
Also, preservatives are often added to make the food last longer, but these aren’t good for cats’ health in general.
Nutritional Values of Mayo for Cats
Mayonnaise could be better for cats in terms of nutrition. Cats can become overweight if they overeat mayo because it is high in calories.
Generally, cat owners should talk to a vet or feline nutritionist before giving their cats human food.
For 100 grams of mayonnaise, here is a simple table with percentages that show how healthy it is:
| Nutrient | Amount per 100g |
| Calories | 680 calories |
| Total Fat | 75 grams |
| Saturated Fat | 10 grams |
| Cholesterol | 40 mg |
| Sodium | 1,400 mg |
| Protein | 1 gram |
The Safe Consumption of Mayo for Cats
Cats can eat mayo safely if they don’t overeat. Your cat should not be in immediate danger if it occasionally eats a small amount of mayonnaise.
Accidental consumption, like a taste or lick occasionally, won’t hurt them. However, it would help if you didn’t give your cat mayo regularly because it could cause digestive problems.
What to Do If Your Cat Eats Mayo
Do not worry if your cat manages to sneak a taste of mayo. Mayo is not naturally dangerous for cats.
But it’s essential to watch your cat to see if it shows any signs of digestive distress or pain. These reactions that might happen after eating mayo are possible:
Signs of a Reaction to Mayo:
- Excessive drooling, also known as hypersalivation
- Vomiting
- Bloating
- Diarrhea
- Lethargy or general unwell appearance
If you notice any of these signs in your cat, you should immediately take them to the vet. It’s best to completely keep mayo from your cat’s food, even though small amounts might not be too bad for them.
How Can I Feed My Cat Mayo?
If you want to give your cat mayo, don’t give them too much. It’s enough to take a teaspoon every few days.
Choose a brand of mayo that doesn’t have any extra salt or sugar added, or even better, make your own using a recipe that cats will enjoy:
Ingredients:
- 1 egg yolk (or the entire egg for cats)
- 1 cup olive oil
- 1 tsp. powdered mustard (optional for cats)
- 2 tsp. fresh-squeezed lemon juice (use vinegar for cats)
- 1 tsp. Water
- ¼ tsp. salt
Steps:
- Leave the oil out of the mix and whisk the rest of the ingredients together.
- Add a few drops of oil at a time and mix the mixture quickly between each addition until it gets thicker and lighter in color.
- Slowly speed up, adding oil until it’s all mixed in.
- Mix the mayo some more until it gets thick.
- After letting it sit for an hour or two, put it in the fridge in a container that won’t allow air in. You can use this homemade mayo for about a week.
Healthy Alternatives
It would be best if you thought about offering your cat healthier snacks that are more in line with the requirements of their diet in place of mayonnaise.
Choose cat treats that are safe for them and maintain a diet that is well-balanced and heavy on meat. High-quality cat food is specifically formulated to fulfill your cat’s dietary requirements without exposing them to the health hazards associated with human condiments.
Final Words
Mayonnaise, also known as “mayo,” should not be fed to your cat. It’s not very good for you, and if your cat overeats it, it could be bad for their health.
It’s best to stay away from mayo for your cat because many other safe and healthy options are available.
It’s essential that your cat is healthy and happy, and you can help them live a long and happy life by choosing foods that are good for them.
A qualified veterinarian is the best person to ask about cat nutrition and other cat-related topics.
