Ingredient Information

Instructions

Tested for Purity. Backed by Science.

Every Fera supplement is NASC certified, made in the USA, 3rd-party tested for safety and potency, certified plastic neutral, and crafted with traceable ingredients. Join us as we set the new standard for pet supplements.

Vet Founded & Formulated

Vet-founded and formulated by Dr. Dulake, Fera Pets combines clinically studied, traditional ingredients with new, innovative ingredients to ensure your pets get the holistic support they need to live happier and healthier lives.

Comfort in Every Form

Choose goat milk for irresistible flavor (even for picky eaters), soft chews for daily ease, or powder for flexibility in multi-pet households. Every Fera formula helps promote relaxation, emotional balance, and calm—without drowsiness or fillers.

Science Over Trends

Many calming products skip trusted ingredients or rely on hemp seed, which offers little effect. Fera uses bioavailable actives like Ashwagandha KSM-66 (6× more in our chews than leading brands) and L-Theanine for real calm and balance.

Questions & Answers

6 Customer Questions

Can you use this daily?

Answer by Chewy • Sep 19, 2023
We recommend giving this Calming supplement for at least 3 days prior to stressful events but recommend giving it for 3-4 weeks to see full calming effects, relaxation, and overall balanced mood. This is not meant to sedate your pet, such as vet prescription drugs, but to induce calmness and reduce stress and anxiety over time. It's important to note that supplements containing GABA, L-Theanine, and Passionflower may not have immediate effects on your pet's behavior. In order to see positive results, it's important to give the supplement to your pet on a long-term basis.

How much is 1 scoop? Is it a tablespoon or teaspoon size amount?

Answer by Chewy • Apr 08, 2024
The scoop is equivalent to 1/2 teaspoon.

Will this make your dog drowsy?

Answer by Chewy • Mar 01, 2024
This supplement is not intended to make your pet drowsy.

What flavor is this powder?

Answer by Chewy • Dec 04, 2023
This supplement has a chicken flavor.

Not for large cats

I looked at several cats trees before selecting this one. I chose it because it specifically said it was good for large cats. It is not. My 16lb boy can't fit in

I looked at several cats trees before selecting this one. I chose it because it specifically said it was good for large cats. It is not. My 16lb boy can't fit in the top 2 perches, he spills out of the top cubby and barely fits through the openings on the bottom cubby. The platforms are small and, even anchored, the whole thing is very wobbly. The only part of this cat tree that is used is the hammock by my 8lb cat. She fits comfortably in that. The big boy does not. Overall, very disappointed in the quality, sturdiness, and that it doesnt work for large cats, as advertised.

Well both cats I tried it on did not like the taste. I had to bury it in a lot of wet food and then it did nothing at all. The 3rd cat doesn't eat wet food so I wasn't able to see if this would tame his aggressive moods.

My GSD is very reactive and anxious. I have noticed an improvement with her, but it is certainly not a "sedative". I don't think it's supposed to be, just want to manage expectations. I would say this improved her ability to be redirected and deescalated with her anxiety, but she is still anxious. She might always be, though.

I would like the product more if the ongoing money gouging did not complicate my financial ability to purchase what I need for Ashton. As with many products purchased thru Chewy quality may be there, purchase sizes for chronic issues are not.

Fera Pets Products are a trusted brand

Through experience we trust the brand, and the products work as intended. One small scoop per day in the morning is all it takes! Thanks so much!

Not the products fault

It's probably not a bad product. I got it go help my little River. But it was too late for much of anything to help her. She stopped eating, and we lost her soon

My corgi wouldn’t eat it.

Unfortunately my corgi that won’t say no to any type of food, treat, or medication would not eat this powder on his food. I tried a few times with no success.

I had low expectations for this but bought it out of desperation. Our cat is pretty old and arthritic and despite being medicated, does a lot of “yelling” for no apparent reason, especially in the middle of the night. Nothing has worked until this powder. It wasn’t immediate but after a few weeks as long as she actually ate her dinner, she was calm all night. Now we can tell if she ate her food or left it because she will be loud if she hasn’t gotten her powder. Total game changer for us

Actually worked!

We have a pittie that has SEVERE anxiety issues. She’s been prescribed Xanax, Zoloft, Prozac, Gabapentin and Trazadone. None of them helped. We’ve worked with her vet for 2 years trying to find something to help her. I decided to randomly try this product with little hope. It works! I’m shocked. She is just chill and less reactive to every single sound she hears. She’s not sleepy or sedated at all. I will purchase this product again for sure if it continues to help her feel less stressed and anxious.
