Can Cats Eat Mushrooms? Are Mushrooms Toxic To Cats?

Can Cats Eat Mushrooms?

Mushrooms are a staple ingredient in a variety of foods, including pizzas, kabobs, pastas, sautés, and omelets. Some people even prefer eating mushrooms as standalone snacks.

Although mushrooms have been around from time immemorial, they’ve garnered tremendous popularity in recent years. That’s due to the growing body of studies citing these fungi for their incredible nutritional profile as well as their ability to treat or prevent certain diseases.

Mushrooms have particularly become popular with vegetarians. Today, it’s almost impossible to miss Portobello burgers or mushroom-based mock meats in restaurant menus or grocery stores.

If you’re a fan of mushrooms and also happens to own a cat, you may often find it difficult to resist the temptation of sharing these delicious meaty fungi with your feline friend. But before you do, it’s important to establish whether mushrooms are safe or even nutritionally beneficial to cats. And that begs the question, can cats have mushrooms?

The short answer is ‘maybe.’ Most store-bought mushrooms are safe for cats. However, the same cannot be said about wild mushrooms. Almost all varieties of wild mushrooms are downright toxic for cats and should never find their way into your cat’s food.

In this post, we shall share everything there is to know about cats and mushrooms, with a special focus on the potential benefits and risks of mushrooms for cats.

Are Mushrooms Bad for Cats?

As we’ve just pointed out, the safety or toxicity of mushrooms for cats mainly depends on the variety of mushrooms your feline friend has eaten. Generally, store-bought mushrooms are safer for cats than wild mushrooms.

But as you shall find, the fact that certain foods are safe for cats doesn’t necessarily make them nutritious. Cats have a dietary evolution that doesn’t allow them to enjoy the nutritional and health benefits in mushrooms the same way humans do.

If you must feed mushrooms to your kitto, always ensure you consult your vet first.

Are Mushrooms Bad for Cats?

Do Cats Love Mushrooms?

Cats are generally uninterested in fruits and vegetables. In most instances where cats demonstrate an interest in fruits and veggies, they’re usually driven by the desire to play and not eat these plant-based foods. That’s only understandable, considering that cats are obligate carnivores.

An obligate carnivore refers to an animal that can live exclusively on a diet made up of animal-based products, such as lean meat, blood, skin, and bones. That’s in contrast to facultative carnivores, which can comfortably supplement with plant-based products.

But if you regularly cook with mushrooms, you must have noticed a heightened level of curiosity in your cat whenever you’re chopping mushrooms in the kitchen. And that may get you wondering, do cats love mushrooms? Yes, cats do love mushrooms and there’s a valid scientific reason why.

To understand why cats love mushrooms, it’s important to familiarize yourself with how a cat’s taste buds work.

cute cat lick her lips

According to food scientists, cats are unable to taste sweetness. That’s because they lack a functional gene which controls sweetness taste receptors. However, they can easily taste savory or umami flavors.

Umami flavor is one of the five basic flavors human taste buds can pick up. The others include Sweet, Salty, Sour, and Bitter.

Now, mushrooms contain significant levels of the amino acid glutamate. Glutamate is a crucial component of umami foods. The fact that cats love umami tastes explains why they would be happy to gorge themselves on mushrooms.

Another reason cats seem attracted to mushrooms is due to the meaty texture of these fungi. Not only do mushrooms feel meaty to the touch, they also feel meaty when chewing. So, an unsuspecting cat may believe that they’re actually eating meat.

Are mushrooms safe for cats then?

The fact that cats are attracted to mushrooms isn’t a valid reason to offer them these fungi. In fact, cats’ profound love for mushrooms is more of a curse than a blessing.

It means that your kitto can easily help himself to mushrooms behind your back. If such mushrooms happen to be toxic, the consequences can be disastrous.

Also, remember that mushrooms are technically plant-based foods. And as we’ve already pointed out, cats are better off with a diet rich in animal protein.

Potential Benefits of Mushrooms for Cats

Mushrooms are loaded with several nutrients that cats can benefit from.

The following are possible ways your cat can benefit from mushrooms.

1. Aiding Heart and Cardiovascular Health

Mushrooms contain a form of soluble dietary fiber known as beta-glucan. This fiber is noted for its ability to improve blood cholesterol and regulate blood sugar.

Therefore, supplementing your cat’s diet with mushrooms may help to keep type 2 diabetes and heart disease at bay.

Besides beta-glucan, mushrooms also boast B vitamins like niacin, riboflavin, and pantothenic acid. These vitamins work synergistically to protect your cat’s health.

B vitamins play roles in other physiological processes too. For instance, niacin aids the digestive system and maintains healthy skin, while riboflavin maintains red blood cells. Pantothenic acid facilitates the secretion of vital hormones and also maintains the nervous system.

2. Prevention of Disease

Type 2 diabetes and heart disease are not the only medical conditions that mushrooms may protect your cat from.

These fungi also contain powerful antioxidants called selenium, which could lower the risks of other chronic diseases like cancer.

3. Flavor Enhancing

You can use mushrooms to enhance the taste of your cat’s food, thanks to the abundant umami flavors in these fungi.

If your kitto has lost his appetite and won’t eat his regular food, mixing some mushrooms into his food might help him regain his appetite.

The following are other essential minerals in mushrooms, along with their potential benefits for cats;


Aids in the manufacture of red blood cells, while also supporting bone health and the nervous system.


Maintains fluid balance and supports heart health. Potassium also supports muscles and the nervous system.


(1) There are minimal scientific findings suggesting that mushrooms are directly beneficial to cats. Many of the potential health and nutritional benefits of mushrooms for cats have been extrapolated from human studies.

Remember that our dietary requirements and physiological mechanisms aren’t exactly similar to that of our canine friends. Therefore, it’s difficult to say with surety whether cats will enjoy the benefits of mushrooms the same way humans do.

(2) Also, the potential health benefits of mushrooms for cats only apply to non-toxic, edible mushroom varieties. Never feed mushrooms to your cat whose safety you cannot vouch for.

What Happens If A Cat Eats Mushrooms?

We’ve just highlighted the various ways cats could benefit from eating mushrooms. But before you share these fungi with your feline friend, it’s important to understand everything that could possibly go wrong.

First off, note that while mushrooms are fungi, they’re generally considered plants. Feeding plant-based foods to cats isn’t a wise idea. That’s because cats are obligate carnivores and their digestive system considers plants as foreign substances.

So, as with most plant-based products, mushrooms can trigger a host of gastrointestinal complications in cats. Common symptoms of gastrointestinal distress include vomiting, diarrhea, and abdominal pain.

However, digestive complications aren’t the only thing that could go wrong if your cat ate mushrooms. Mushrooms, particularly the wild varieties, contain amanitins, muscarines and isoxazoles. These compounds may cause mushroom poisoning in cats.

Some of the side effects of mushroom poisoning include;

Symptoms of gastrointestinal distress, such as nausea, vomiting, loss of appetite, diarrhea, flatulence, and abdominal pain or discomfort,
Dehydration, which often results from vomiting and/or diarrhea,
Extreme sensitivity to sound and light,
Poor balance and coordination,
Jaundice (yellowing of the eyes or skin), resulting from liver toxicity,
Irregular heartbeats.

But there’s also the question of raw versus cooked mushrooms, and which between these options is safer for cats.

Cats can eat mushrooms, raw or cooked, provided the fungi are free from the compounds known to cause mushroom toxicity in cats.

However, you’re better off feeding your cat cooked as opposed to raw mushrooms, and for obvious reasons.

It’s true that raw mushrooms retain most of their nutritional elements, including those that would have been destroyed by cooking. But raw mushrooms also tend to contain lingering bacteria and parasites that might find their way into your cat’s digestive system.

Can cats eat raw mushrooms?

Are cooked mushrooms OK for cats then?

Since raw mushrooms are discouraged for cats, you may now be wondering, can cats eat cooked mushrooms? Yes, the best way to feed mushroom to your cat is to cook them first.

That begs the question, can cats eat mushrooms and onions?

No, onions rank among the top spices that cats shouldn’t eat. So, cats shouldn’t eat any onion-containing foods, including mushrooms.

Can cats eat mushroom soup?

The fact that cats can eat cooked mushrooms also means they can comfortably eat mushroom soup. However, keep the portions low as too much mushroom soup might induce diarrhea.

Still on cooked mushrooms for cats, you might be wondering, can cats eat mushrooms from pizza?

Regular pizza contains numerous ingredients that cats shouldn’t eat, such as flour, dairy products, and spices. So, mushrooms from pizza aren’t safe for cats.

Dried mushrooms usually have considerably high concentrations of compounds. Which means that if these mushrooms happen to contain any toxins, then they could be more poisonous to cats than wet mushrooms.

How much mushroom can cats eat?

When it comes to mushrooms for cats, moderation is key. There’s no hard and fast rule on the quantity of mushroom your cat can eat, as it depends on factors like the animal’s age and medical condition.

The convention is to start with the tiniest bits and observe how your cat reacts before possibly increasing the servings.

So, Can Wild Mushrooms Hurt Cats?

Yes, wild mushrooms are highly poisonous to cats. Even some edible mushrooms considered safe for humans could still harm your kitto.

If you ever suspect that your cat has eaten mushrooms, the best course of action is to visit the vet immediately. The vet will examine the animal and decide on the most appropriate treatment plan.

As a responsible cat owner, you can take certain proactive measures to reduce your cat’s exposure to mushrooms.

For instance, keep mushrooms in the fridge to prevent your cat from accessing them. Also, seal trash cans tightly and clean plates thoroughly to prevent the animal from nibbling on leftovers after a mushroom meal.

It’s also advisable to check your backyard or lawn occasionally for any sprouting mushrooms. But if you can’t seem to find the time to do so, consider spraying the area with cat deterrents or installing motion-activated sprinklers.
