Can cats eat mushrooms, or will it get them in truffle?

While the exclusively carnivorous felines hardly ever nibble on plants, there’s a certain substance called glutamate in mushrooms that cats find appetising. But are fungi a food fit for felines? Since some mushrooms contain toxins, cat parents are apprehensive about including them in their pet’s meal plan, even as treats. So, can cats eat mushrooms, or do the risks outweigh the gains? Let’s find out!

Why do cats eat mushrooms?

Unlike humans or dogs, cats aren’t omnivorous, and their taste buds are limited to certain flavours. Because they’re evolutionarily conditioned to feast on meat, felines respond more strongly to savoury than sweet tastes. 

Mushrooms are rich in glutamate, an amino acid that provides a distinct umami taste that entices felines. Your cat’s keen sense of smell can detect the delicious substance and become drawn to it.

Whether cats can eat mushrooms depends on the variety. Commercially sold mushrooms that are safe for humans are also fit for cats. You can give them to your pet as a treat without any concerns.

Mushrooms are rich in amino acids, selenium, vitamin B, and antioxidants. Amino acids are essential nutrients in the feline diet responsible for their heart, brain, and eye function. 

While some plants and fungi contain non-essential and essential amino acids, their bioavailability is limited. Animal protein is the only viable source of essential nutrients, like taurine and arginine, that sustain your cat’s metabolism, so it can’t be replaced with plant protein. Cats can eat commercially distributed mushrooms, but they won’t experience any real health benefits.

Wild mushrooms are an entirely different story. Since many of them contain toxic substances, the forest fungi are potentially life-threatening for both humans and felines. 

If you let your cat roam outside, chances are they’ll come across a toxic wild mushroom. The seven deadliest mushrooms that can be found in our neck of the woods are:

  1. Deadly webcap or Cortinarius rubellus
  2. Angel's wings or Pleurocybella porrigens
  3. Death cap or Amanita phalloides
  4. Funeral bell or Galerina marginata 
  5. Destroying angel or Amanita virosa
  6. Panther cap or Amanita pantherina
  7. Fool's funnel or Clitocybe rivulosa

Mushroom poisoning—symptoms and treatment

As the highly dramatic names suggest, wild mushrooms can be lethal to cats. The symptoms of food poisoning can manifest quickly, only a few hours after ingestion, depending on the variety. Your cat will most likely experience:

  • Excessive salivation
  • Vomiting and nausea
  • Sensory issues
  • Yellowing of the eyes and skin

If your cat has access to a wooded area and starts demonstrating these symptoms, take them to the emergency room immediately. The longer the toxins stay in your cat’s system, the more damage they’ll cause to their internal organs. 

Your cat will be given a dose of activated charcoal to prevent further absorption of harmful substances. The vet may even induce vomiting upon arrival to remove the toxins from your pet’s stomach. In some cases, gastric lavage is required to flush the toxins from the digestive system.

Once your cat is stable, they’ll need plenty of rest and rehydration.

How to serve mushrooms to cats safely

If your cat loses their whiskers every time you’re making creamy mushroom soup, consider giving them a taste. Any variety that you’d use in your kitchen is also safe for cats, including:

  • White button mushroom
  • Portobello mushroom
  • Maitake mushroom
  • Shiitake mushroom
  • Cremini mushroom
  • Hedgehog mushroom
  • Enoki mushroom
  • Oyster mushroom

The preparation method is different because cats have more sensitive stomachs. When preparing mushrooms for your feline companion, make sure you:

  1. Wash the mushrooms thoroughly
  2. Boil them in water without seasoning
  3. Wait for them to cool at room temperature
  4. Cut them into tiny, bite-sized pieces

The potential downside to feeding your cat mushrooms is that they may develop a preference for the fungi. If they’re an indoor-only pet, it won’t pose a problem, but if you allow them to go outside, they could end up eating a poisonous wild mushroom.

Should kittens eat mushrooms?

Kittens require a delicate balance of fat, protein, and calcium to develop at a healthy rate. In the first three to four weeks, they get all the nutrients from their mother or, in her absence, from a specially formulated milk supplement (KMR)

When they start weaning, you can let them try mushrooms or other solid foods, but in limited amounts. Kitten food must be rich in essential nutrients to sustain their weight development and muscle growth while safeguarding their delicate tummies. Once they reach the 12-month mark, they can try different adult cat food products and endure more variety in their diet!

What should you feed your feline companion?

There’s much debate about what the best feline diet is or rather how to achieve the optimal nutritional balance. The recommended ratio of macronutrients is depicted in the table below:

Nutrient

Recommended intake

Protein

More than 50%

Fat

Up to 20%

Carbohydrates

Less than 3%

To achieve the desirable allowances of fat and protein, cat parents opt for one of the three popular feline meal plans:

  1. Raw food
  2. Dry food
  3. Wet food

Raw food

In the wild, felines would get the ideal protein-to-fat ratio by feasting on birds, rodents, or other freshly killed prey. Following the natural diet of felines, some cat parents believe that raw food is the only suitable replacement for domesticated cats. 

The so-called “bones and raw food” diet (B.A.R.F.) looks good on paper, especially for cats struggling with obesity and diabetes, but in reality, it can be dangerous.

Raw meat and other raw ingredients, like uncooked eggs and unpasteurised milk, are the ideal breeding ground for several microbial pathogens. If your cat is exposed to raw food directly or through a contaminated surface, they can get infected with E. coli, Listeria, or Salmonella.

The signs of infection will manifest in the 12–72 hours after consumption in the form of:

Not only is the disease difficult on your cat, but it can potentially spread to the entire household. Additionally, no studies have shown that an entirely raw diet is superior to using processed foods in terms of nourishment. In some cases, it can even lead to nutritional imbalance since it’s difficult to maintain the ideal nutrient ratio in homemade raw meals. That’s why it’s better to rely on processed cat food carefully formulated to provide nourishment.

Dry cat food

Dry cat food is heavily processed and contains grain and other fillers that add to the calorie content. Some cats prefer the texture and aroma, but you should strive to correct that poor eating habit. 

A dry-food-only diet lacks moisture which can result in chronic dehydration. Without water, felines can develop problems with digestion and urinary tract disease

Dry biscuits and other high-calorie foods can contribute to the development of metabolic dysfunction. That’s why wet food is a healthier choice for your pet, especially if they have genetic predispositions for particular conditions. For example, Maine Coons are prone to diabetes malleus and should avoid kibble.

Wet cat food

High-quality moist cat food (and some semi-moist products) are filled with essential nutrients, such as:

  • Water
  • Animal protein
  • Omega-3 and omega-6 fatty acids
  • Natural vitamins and minerals

When compared to kibble or raw bones and meat, wet food is much more nourishing. But not all cats take a liking to it at first. Felines who haven’t been exposed to wet food during the weaning period can react poorly to the slimy texture. Luckily, it’s not too late to correct the behaviour! You can try the following tips:

  1. Soak your finger in the product and allow them to smell or lick it off
  2. Mix wet food with kibble or other ingredients they like
  3. Warm the meal in the microwave before serving
  4. Add soup or broth to the meal to enhance the aroma
  5. Clean their bowl thoroughly after each meal to prevent whisker fatigue
  6. Limit their access to food to stop them from picking at their meals

What fruits and veggies are toxic to cats?

Besides wild mushrooms, some fruits and vegetables are also toxic to cats, such as:

  • GrapesGrapes and raisins can induce vomiting, diarrhoea, and restlessness in cats. If you regularly feed them to your feline, they’re at risk of developing kidney disease. We don’t know exactly what it is in grapes that causes such severe reactions in cats, but it’s present in both fresh and dried grapes and grape byproducts
  • Citrus fruits—Cats aren’t particularly attracted to the intense smell of citric acid, but even tactile contact can cause skin irritations in more sensitive felines. If consumed regularly, these fruits can cause irreparable damage to your cat’s kidneys, as well as mild to severe indigestion. Minutes after eating an orange segment, felines can suffer from nausea, vomiting, and diarrhoea
  • Allium vegetables—Plants from the allium family, especially garlic, onions, and chives, are y toxic to cats. These veggies are filled with thiosulphate, a substance that directly attacks the feline’s red blood cells. If you like treating your cat to a homemade meal from time to time, avoid these vegetables. Both fresh and powdered forms can cause anaemia and kidney disease

Does that mean all fruit is forbidden for felines? Certainly not! It’s okay to feed your cat some fruit and veggies in limited servings. High-fibre fruits, such as apples, bananas, pumpkins, and strawberries, can even help with indigestion or chronic bowel inflammations

Even with the minor health benefits, fruits and vegetables are mostly useless to cats. All the micronutrients contained in plants (and fungi) are already present in meat. The better treat choice would be fish (tuna, salmon, prawns, sardines) or chicken (including liver).

Other food items your cat should avoid

Most of these foods and ingredients (except caffeine and alcohol) won’t cause immediate damage but are harmful in the long run. Cats must not eat the following items regularly (or at all in some instances):

  1. Dairy—Regardless of the age or breed, most cats lack the digestive enzyme required for processing lactose, so milk, cheese, and other dairy products are too much for them. Despite the natural intolerance, felines are drawn to fatty acids in milk and will try to get their paws on it. Don’t cave before the incessant meowing because dairy will give them severe indigestion. You can let them have a tiny bit of lactose-free milk or yoghurt but don’t encourage the habit
  2. Processed meatCured and processed meats contain high amounts of sodium and saturated fats. If you tend to share a charcuterie board with your pet, it may disrupt their metabolism after a while, especially if they’re older. Senior cats often develop hypertension and hyperthyroidism, and fatty meats will only speed up the process. Some cat food manufacturers use small amounts of ham in their products as a taste enhancer but other than that—avoid giving your cat meat derivatives
  3. PorkPork is the best option because of the high percentage of saturated fats (14 grams per 100 grams). Fish and chicken are much healthier alternatives since they have an equal allowance of animal protein and are less fatty
  4. Yeast and dough—The feline digestive tract can’t fully digest bread dough, and the residue can linger in their stomach for days, causing abdominal discomfort and constipation. In some cases, the remaining yeast can ferment in their stomach and produce alcohol. Ethanol is highly poisonous to cats, and even a tiny amount could put them in a coma
  5. Chocolate, coffee, and tea—Caffeine poisoning in cats manifests in muscle tremors, heavy breathing, heart palpitations, and extreme restlessness. In severe cases, it can even lead to seizures. To ensure your cat’s safety, try not to leave your cup of tea or java on the table without supervision—it’ll be too tempting for the more curious cat and potentially end with a rushed trip to the vet
