Can Cats Eat Mushrooms?

While some mushrooms are safe for cats, it's generally best to avoid feeding them to your feline friend without veterinarian guidance.

While some mushrooms are safe for cats, it's crucial to ensure they are of the edible variety. Store-bought mushrooms like white button, cremini, and portobello are generally safe in small amounts, but wild mushrooms can be dangerous and should be avoided altogether. If you're looking for a health supplement for your cat, there may be alternative options that are safer and more effective.

  • Avoid Wild Mushrooms – Never let your cat eat wild mushrooms, as many can be toxic and even fatal.
  • Stick to Safe Varieties – Only offer mushrooms that are proven safe, like white button, cremini, or portobello mushrooms, and only in moderation.
  • Consult Your Vet – If you're unsure about a mushroom's safety or if your cat shows signs of illness after consuming one, contact your vet immediately.

This article covers the essential aspects of fungi for felines, answering the question "can cats eat mushrooms?" Let's take a look.

Can Cats Eat Mushrooms? Yes & No.

Certain mushrooms, like those commonly found in grocery stores, are safe for cats in moderation and can even offer nutritional benefits. These mushrooms contain fiber, vitamins, and antioxidants, which can support your cat's overall health when served properly. However, it’s important to avoid any seasoning, butter, or oils, as these additions can upset your cat’s stomach or be harmful.

Many wild mushrooms, including varieties like amanita and galerina, can be extremely toxic to cats and lead to serious health issues. These mushrooms often contain potent toxins that can cause symptoms ranging from vomiting and diarrhea to liver failure and even death. Symptoms of mushroom poisoning may not appear immediately, so it’s essential to monitor your cat closely if they’ve been exposed to wild mushrooms and seek immediate veterinary care.

What Happens When Cats Eat Mushrooms They Shouldn't?

When cats eat mushrooms they shouldn’t, they can experience a range of symptoms, from mild digestive upset to severe organ damage. Prompt treatment is essential to prevent long-term health issues or even death, depending on the type of mushroom consumed.

Signs of Mushroom Poisoning in Cats

Key symptoms to watch for include:

  • Vomiting
  • Diarrhea
  • Loss of appetite
  • Lethargy
  • Jaundice (yellowing of the skin or eyes)
  • Seizures

Symptoms may appear within 6–12 hours and can progress rapidly, so seek veterinary help immediately if your cat shows any signs of poisoning.

What Specific Mushrooms Can Cats Eat?

While this is not a substitute for veterinary guidance, these general guidelines can help identify which mushrooms are typically safe for cats. Always consult your vet before introducing any new food into your cat’s diet to ensure it’s appropriate for their health needs.

  • White Button Mushrooms – Commonly found in stores, these are generally safe for cats when given in small amounts.
  • Cremini Mushrooms – Also known as baby bella mushrooms, these are similar to white buttons and safe for cats in moderation.
  • Portobello Mushrooms – A larger variety of cremini, they are safe when served plain and in moderation.
  • Shiitake Mushrooms – Known for their nutritional benefits, these mushrooms can be safe when prepared properly.

While mushrooms can offer some health benefits, they should not be a regular part of your cat’s diet. It's best to serve them occasionally, in small amounts, and without any additives like oils or seasonings. For a safer alternative, consider vet-approved supplements that incorporate mushrooms known to be beneficial and safe for cats.

Should Cats Ever Eat Wild Mushrooms?

Wild mushrooms are dangerous for cats and should always be avoided. Many varieties contain toxins that can cause severe health issues, and identifying safe mushrooms can be nearly impossible without expert knowledge. Even a small amount can lead to poisoning, so it’s crucial to keep your cat away from any wild mushrooms they may encounter.

Do Mushrooms Seem Tasty to Cats?

Cats are obligate carnivores and typically have no interest in mushrooms. However, they may nibble on them out of curiosity or if they have been introduced to them through their diet. It's important to monitor your cat to ensure they don’t consume something harmful by mistake.

Conclusion: Can Cats Eat Mushrooms Afterall?

While some mushrooms are safe for cats in moderation, such as common varieties like white button or cremini mushrooms, caution is key. Wild mushrooms are a major risk and should always be avoided due to the potential for toxicity. If you do choose to offer mushrooms to your cat, stick to store-bought varieties, serve them plain, and consult your vet to ensure they are a suitable addition to your pet's diet.

Can Cats Eat Raw Mushrooms?

Raw mushrooms can pose a risk to cats, especially if they are wild or contain toxins. Even store-bought mushrooms should be prepared properly, and cooking is recommended to eliminate potential bacteria or harmful compounds. Always consult with your vet before offering raw mushrooms to your cat.

Can Cats Eat Magic Mushrooms?

Magic mushrooms are highly toxic to cats and should never be consumed. They contain psilocybin, a substance that can cause hallucinations, seizures, and serious health problems. If you suspect your cat has ingested magic mushrooms, seek immediate veterinary care.

Can Cats Eat Cooked Mushrooms?

Cooked mushrooms are generally safer for cats than raw ones, provided they are prepared without harmful ingredients like oils, butter, or seasoning. Stick to safe varieties like white button or cremini mushrooms, and always serve them in moderation. However, cooking does not remove all risks, so consultation with your vet is advised.

Can Cats Eat Amanita Mushrooms?

Amanita mushrooms are extremely toxic to cats and should be avoided at all costs. Even small amounts of these mushrooms can lead to severe liver failure, vomiting, or death. If you suspect your cat has eaten any part of an Amanita mushroom, contact your vet immediately.

What if Cats Eat Very Small Quantities of Dangerous Mushrooms?

Even small quantities of dangerous mushrooms can have harmful effects on cats. Symptoms may be delayed, and even minimal exposure to toxic mushrooms can lead to serious health issues. If your cat consumes any potentially harmful mushrooms, seek veterinary assistance as soon as possible, even if the amount seems small.
