Tummy aches, loose stool, gas, low energy—it always hurts to see our pets suffer from intestinal issues. It’s why we created Fera’s Probiotics + Prebiotics to keep your pet's digestive system humming along perfectly. 

Probiotics are beneficial microorganisms that help control the balance of the digestive system, aid in reducing loose stool due to environmental or dietary changes, and support the immune system and skin health.

Dr. Dulake custom-picked 12 living strains with powerful dosing of 5 billion CFUs to actually make a positive difference in your pet's digestive health. Our probiotics also include organic prebiotics that supports normal microbial balance and the growth of beneficial bacteria in your pet’s intestines.

Best of all, this flavorless powder easily mixes into your pet’s food. It’s easy and effective!

  • Gut health: Promotes healthy intestinal tract, digestion, and normal stools. 
  • Immunity: 12 powerful strains of good bacteria promote a healthy microbiome and immune system. 
  • Skin + Coat: Supports skin health and soothes skin-related issues associated with seasonal allergies.
  • Energy: Increases gut flora for an energy boost.

Not all strains are created equal. When it came time to formulate our probiotics, Dr. Dulake made sure each strain held a specific function and when combined, worked in conjunction to enhance your pet's digestive health.

S. boulardii calms the intestines and protects them from pathogens that can damage your pet's intestinal walls. B. Infantis breaks down complex carbohydrates that gut cells are unable to digest.

Frequently Asked Questions

The scoop is 1.2 grams or 2.5cc, which is equivalent to ½ teaspoon.

Our USDA Organic Probiotic with Prebiotics has 60 servings (scoops) per container. We recommend 1 scoop a day if your pet is between 15-60 lbs.

All of FERA's products are manufactured in the USA. All strains in our probiotics are from the US. Our Organic Prebiotics are from: FOS (Belgium), Inulin (Mexico), and Acacia (Senegal). It is manufactured in an FDA-registered GMP-compliant facility, third-party tested, and NASC certified.

Probiotics can be defined as living microorganisms, that when ingested in certain numbers, confer health benefits beyond that of their inherent nutritional value. The microbes used in our probiotics are live non‐pathogenic organisms, such as various Bifidobacterium and Lactobacillus species, Enterococcus faecium, and non‐bacterial organisms such as the non‐pathogenic yeast Saccharomyces boulardii. Our probiotic formula is custom formulated by our veterinarian who recommends using a broad spectrum probiotic to bring balance to the gut microbiome. Each strain in our probiotic powder is proven to be beneficial for both cats and dogs and handpicked by our veterinarian. We also include prebiotics, which are non-digestible carbohydrates that modulate the intestinal microbiota and promote the growth of beneficial microorganisms in the intestines, which many other probiotics do not include.

The probiotic container is normally about half filled. We provide a longer handle scoop and wide rim bottle for ease of scooping, which requires a larger bottle. Each probiotic bottle contains 60 servings (ex: a pet that weighs 15-60 lbs will have 60 days worth).

If your pet was having normal stools prior to use, we ask that you stop using the probiotics and wait one week before reintroducing it. We always recommend starting at HALF the recommended dose. So if your pet is supposed to receive 1 scoop daily, please start at 1/2 scoop for a few weeks. We do recommend only introducing one supplement/treat at a time so we are not confused about what could be causing any diarrhea. We also recommend giving our Probiotics for 4-6 weeks to allow the GOOD bacteria to inhabit the gut and see positive results.

Our USDA Organic Probiotics with Prebiotics powder is flavorless and can easily be mixed in with your pets food.

Our USDA Organic Probiotics with Prebiotics does not need to be refrigerated as long as they are stored in a cool (below 72 degrees), dry place. You are definitely welcome to refrigerate it if the storage conditions fluctuate as this will help maintain their potency.

Yes, it can be mixed with water. We recommend room temperature or cold water to maintain potency of the living beneficial bacteria. Please do not use warm or hot water.

During production, we add a surplus/overage of the amount of LIVING bacteria in our Probiotic powder to account for the natural decline in numbers secondary to transit, storage, and stomach acid. Keeping the probiotics in a cool, dry place (< 72 degrees) to maintain good stability is recommended and can be refrigerated to preserve potency if humidity and heat is an issue.

There are 3 main reasons for itchy skin:
1. flea allergy
2. food allergy
3. environmental allergy (atopy).

We have seen improvement with itching and overall skin health, especially if it is related to food allergies. But we always recommend consulting with your veterinarian to rule out all other causes of itchiness, especially if it does not improve with our probiotics.

Yes! NO ADDITIVES, FILLERS OR PRESERVATIVES: All-vegan probiotic, no wheat, corn, soy. gluten-free, grain-free, dairy- free. Our powder is all natural and hypoallergenic.

Our containers are BPA free, FDA compliant, recyclable, and safe for food contact.

    ⭐️⭐️⭐️⭐️⭐️ Product and Customer Service

    This product is great. Our little buddy loves it, it keeps his digestive system regular and always gets complimented about how soft his coat is. Also we recently got a bad container that was damaged. Small amount of powder did escape while all tamper proof seals were intact. We contacted Fera’s customer service to see what can be done because Amazon automatically closed off the option to return/replace/refund the product. Big thanks to Ana for helping us get a replacement. Her kindness and professionalism exemplifies why we trust this company and their products

    No More Tummy Troubles

    USDA Organic Probiotics with Prebiotics by Fera Pets keeps my pup's digestive system happy and healthy. My girl is a pup who enjoys sneaking more than a few nibbles of her big brother’s kibble and pulling up and eating clumps of grass and mud. These activities usually result in an upset tummy and soft stools. I discovered Probiotics + Prebiotics by Fera Pets helps her intestinal issues. Made with twelve strains of good bacteria in one flavorless powder, it supports her digestive health without effecting the taste of her food. Adding it to her meals everyday has been a game changer!
