What You'll Learn

Some mushrooms are toxic to cats
Cats are attracted to mushrooms because they have a similar taste and smell to meat. This is due to the presence of an amino acid called glutamate, which provides a savoury taste known as umami. While some mushrooms are safe for cats to consume, others are toxic and can cause severe health complications or even death. It is important to treat all mushrooms that have not been purchased for human consumption as toxic and to seek immediate veterinary care if your cat ingests any mushrooms.
Mushrooms contain toxins that can be categorised into four groups: gastrointestinal (GI) toxins, hepatotoxic toxins, nephrotoxic toxins, and neurotoxic toxins. Gastrointestinal toxins can cause vomiting, diarrhoea, weakness, dehydration, slow heart rate, and respiratory problems. Hepatotoxic toxins affect the liver and can lead to liver failure and death. Amanita mushrooms, also known as death caps or death angels, belong to this category. Nephrotoxic toxins affect the kidneys and can cause nausea, vomiting, increased drinking and urination, and dehydration. Neurotoxic toxins affect the nervous system and can cause weakness, lack of coordination, tremors, hallucinations, disorientation, agitation, drooling, vomiting, and seizures.
The specific symptoms and their onset depend on the mushroom species and the amount ingested. Some mushrooms can affect cats within 15-30 minutes, while others may take up to 24 hours to show noticeable effects. If you suspect your cat has ingested mushrooms, it is important to seek immediate veterinary care and provide as much information as possible, including the type of mushroom, the amount ingested, and the time of ingestion.
While commercially sold mushrooms that are safe for human consumption are generally considered safe for cats, it is still best to avoid feeding mushrooms to your cat regularly. Mushrooms offer limited nutritional benefits to cats and may increase their risk of ingesting wild or poisonous mushrooms. Wild mushrooms can be extremely poisonous to cats, and only experienced pickers can recognise which ones are safe to eat. Therefore, it is crucial to prevent your cat from ingesting any mushrooms from outdoors or unknown sources.

Symptoms of mushroom poisoning in cats
While some mushrooms are safe for cats to consume, others can be toxic and lead to severe health complications. It is best to treat all mushrooms that are not intended for human consumption as toxic. The symptoms of mushroom poisoning in cats vary depending on the species of mushroom consumed and the amount ingested. Some mushrooms can affect cats within 15-30 minutes of ingestion, while others may take up to 24 hours or even longer for symptoms to appear.
One category of toxic mushrooms causes gastrointestinal issues, resulting in an upset stomach, vomiting, and diarrhea. These mushrooms can also lead to dehydration, a slow heart rate, and respiratory problems. Another category affects the liver, causing liver failure, which can be deadly. Symptoms of liver toxicity include vomiting, diarrhea, jaundice, lethargy, weakness, and loss of appetite. Some mushrooms can also cause kidney toxicity, leading to increased drinking and urination, nausea, vomiting, and dehydration.
Neurotoxic mushrooms can cause neurological issues such as weakness, lack of coordination, tremors, hallucinations, vocalizations, disorientation, agitation, altered mentation, drooling, vomiting, and seizures. It is important to note that neurotoxic mushrooms grow naturally in the Pacific Northwest. If you suspect your cat has ingested mushrooms, it is crucial to seek immediate veterinary care and, if possible, bring a sample of the mushroom for identification.
The treatment for mushroom poisoning in cats typically involves general supportive care to reduce damage to internal organs while the body clears the toxin. Inducing vomiting and using activated charcoal can help remove the toxin from the body. In some cases, hospitalization may be required for intravenous fluid therapy and other treatments.

Safe mushrooms for cats to eat
While some mushrooms are safe for cats to eat, it is important to exercise caution as many mushrooms are toxic and can be dangerous or even fatal for cats. It is recommended that mushrooms are not a regular part of a cat's diet, but if they do eat a safe variety on occasion, this is not a cause for concern.
Cats are attracted to the smell of mushrooms because they contain an amino acid called glutamate, which has a similar taste and smell to meat. However, it is important to note that mushrooms do not offer any nutritional benefits to cats. In fact, they can cause an upset stomach if consumed in large quantities.
If you are unsure about whether a mushroom is safe for your cat to eat, it is best to consult your veterinarian or a veterinary poisons service. It is also important to treat all wild mushrooms as toxic and to prevent your cat from eating any mushrooms that you have not identified as safe. North America is home to over 100 species of poisonous mushrooms, including Amanita, Galerina, and Lepiota. These mushrooms can cause serious or even life-threatening illnesses in cats, with symptoms including vomiting, diarrhoea, dehydration, weakness, and lethargy.
Some common mushrooms that are safe for cats to eat include white or button mushrooms, lion's mane, and cordyceps. Culinary mushrooms that are well-cooked are also mostly safe for cats and can provide health benefits. However, raw mushrooms should be avoided as they are harder for cats to digest and may have come into contact with toxins or other substances that could make your cat sick.
