Formulated by a Veterinarian

As a veterinarian, acupuncturist and animal lover, Fera cofounder Michelle Dulake was shocked when she couldn’t find pet supplements with all the qualities she demanded for her patients. She also hated seeing people waste money on ineffective supplements that weren’t helping their pets. So she partnered with her best friend Emily to start Fera Pet Organics and set a new standard for pet supplements.

Questions & Answers

10 Customer Questions

Are the mushrooms extracted, and how many mg of each mushroom?
Answer by ChewyFeb 10, 2022
Fera Pet Organics uses real mushrooms, organically cultivated and naturally grown, free from heavy metals and agricultural chemicals, certified organic and Kosher. We only use organic mushrooms (fruiting bodies) with high levels of beta-d-glucan. No mycelium, no grain, no starch. There is a total of 500mg per scoop. Each scoop contains: Organic Red Reishi - 125mg Organic Lions Mane - 135mg Organic Shiitake - 125mg Organic Turkey Tail - 25mg Organic Maitake - 25mg Organic Cordyceps - 25mg Organic Tremella - 10mg Organic Chaga - 10mg Organic Poria - 10mg Organic Oyster - 10mg

Why is this not safe for human consumption? What is the quality of the ingredients?
Answer by ChewySep 12, 2021
The mushroom blend is made with human grade ingredients and though technically it is safe for human consumption, they are required to put this on the label per the NASC (National Animal Supplement Council).

How many teaspoons is the scoop?
Answer by ChewyJun 17, 2021
Each scoop measures 0.5 grams. The 2.12 ounce bottle contains 120 scoops.

What parts of the mushroom are used in this supplement: fruiting body, mycelium, or both?
Answer by ChewyAug 26, 2021
This supplement uses 100% organic fruiting bodies.

so expensive for the size you get

For $34.95 is exactly what I paid. This container is small! And it’s only just about half full! I post pictures with this review and the picture of the inside of the container. I also took a size comparison to a normal size bic lighter and to zesty paws in pet honesty containers. I literally haven’t used it one time and that’s how full it came. I’m just literally mind blown that I spent $35 on this half full if that. It’s not even half full. small container.

Great supplement

I've been wanting to try a mushroom supplement to help with Ryn's immune system and GI track. She's been on it for couple of weeks now and her poos are better she likes the taste of it on her food!

Shroom what?

I started Ryn on this supplement and I have noticed her poos are better already. She's only been on it a couple of weeks now though but does seem to enjoy it sprinkled on her food!

Love this mushroom supplement!

I have been hearing about the benefits of mushrooms and been wanting to add this superfood to my dogs diet for a while now. They wont eat the mushrooms I cook them but they will eat this supplement which you just sprinkle and mix in with their food. I love the high quality ingredients and all the benefits that this product does for their immune system. Prevention is key to a long and healthy life.

Not clear what is the effect

Ordered this product after reading positive reviews. Did not help or improved anything in overall my cats health, one of the cats got allergic reaction. So Chewy customer service helped us

Awesome product!

Received this product to review. I feel it helped a lot with the overall health and wellness of my pets. I kind of wish it wasnt a powder just because to get the right amount it seems like a bit too much on top of their food. They ate it with no issues.

Great supplement

Such a great supplement to add into your pets meal. I also love that this same product can be use for your cats as well. I love when products are safe for both pets and both can benefit from!

A wonderful addition to your cat's diet!

This has been a wonderful addition to our cats diet. It includes ingredients not in any other supplements so it can be safely combined with others as well or used alone. It comes in a powdered form so you can mix it in with some wet food which they enjoy.

Love this product!

Indie loves having this product sprinkled into her raw food. I love how many different types of mushrooms are included in it, and that they use all organic ingredients. Indie is picky, and never seems to notice it in her food, 10/10 recommend!
