Behind the Science

The Science Behind Reducing Allergens in Cats

"Research shows that eggs from chickens exposed to domestic shorthair cats can reduce Fel d1 allergens. Fel d1 is the major allergen found in cats, responsible for allergic reactions in up to 95% of people with cat allergies" (Ebenezer Satyaraj and colleagues 68-73, 2019)

What Is Fel d1?

Fel d1 is the primary allergen found in cats. This protein is present in their saliva and fur, triggering allergic reactions in sensitive individuals.

How Our Product Reduces Allergens

Chickens exposed to Fel d1 produce an antibody called "IGY" that attaches to the Fel d1 protein, reducing its effectiveness as an allergen. This results in lower allergen levels in cat fur and saliva.

Our Commitment to Ethical Practices

We ensure chickens are safely exposed to Fel d1, without harm. Through supervised interactions between cats and chickens, we maximize the production of anti-Fel d1 antibodies, all while keeping both animals safe during the process.

Our Farm and Safety Procedures

At SAFELINE Pet, we prioritize the highest-quality products for feline health, starting with ethical sourcing. Our farmers follow USDA organic guidelines and strict biosecurity measures from the VDH and CDC. They provide a nutritious diet from a local, family-owned feed supplier. Our partnering farm, home to over 20 cats, ensures ethical exposure of chickens to the Fel d1 allergen, allowing cats to naturally cohabitate while protecting the flock from pests. We uphold humane and ethical care for all animals so you can confidently care for your cat.

Avian Influenza (H5N1) Safety Measures

We recognize concerns regarding H5N1 "Bird Flu." According to the Virginia Department of Health, no cases have been detected in Virginia’s domestic animals, including in Dayton and Roanoke, where we source our eggs. SAFELINE’s facility exclusively processes chicken eggs, eliminating cross-contamination risks.

Our Safety Process:

Pasteurization: Eggs are heated to 165°F with an immersion circulator, then rapidly cooled and freeze-dried.
Biosecurity: Fully enclosed coops, visitor restrictions, rodent control, routine cleaning, PPE use, and vigilant health monitoring safeguard our chickens and cats.

Our Process

We use a proprietary sugar blend to preserve beneficial egg proteins while deactivating harmful ones. This blend supports urinary tract health and allergy relief without affecting glucose levels, making it safe for diabetic cats.

Great product

Product makes a difference with our allergies and cats love the taste. Only complaint is the shipping time.

Really works

It really works

Great product no issues with product, cat eats with wet food each night. Very pleased with results. Took extended time to receive product with second order.

Never shipped

I placed an order for two cat egg powders on May 26, and it’s now June 20. It still hasn’t even shipped. I sent an email yesterday and haven’t received any response. At this point, the lack of communication and the extreme delay are beyond frustrating. It’s honestly outrageous to wait this long with absolutely no update. I’ve never experienced anything like this, and I’m extremely disappointed.

Hi Yunuen,

We are so sorry for the delay with your order and for the lack of communication, we completely understand your frustration, and you’re absolutely right to feel disappointed.

We’re a very small team of just two people, balancing this business alongside full-time jobs to help make ends meet. While that’s no excuse for the delay or the lack of updates, we do want to be transparent and let you know that your order was held up due to an unexpected issue in our manufacturing process. The good news is that the issue has now been resolved, and we’re working hard to get your order, and all others, out as soon as possible.

As a small token of apology, we’ve refunded your shipping costs for the inconvenience. We know this doesn’t make up for the wait or the silence, but please know how truly sorry we are. Your support means the world to us, and we’re doing everything we can to make things right.

Thank you so much for your patience.

Warm regards,
SaFeline pet

Working great so far

How long does it take to feel a reduction in my allergy symptoms?

After around 3 weeks of daily feeding to your cat, you may start to feel relief from your cat allergy symptoms.

What are the directions for feeding my cat the supplement?

Feed it to your cat once a day everyday. Add one scoop (one teaspoon) of the powder supplement into your cat’s wet or dry food and mix thoroughly. Add a little bit of water to the dry food if the powder supplement is not adhering. For kittens under 10 months old, mix in a half scoop (1/2 teaspoon) to their wet/dry food.

Is SaFeline pet’s food topper safe for my cat?

Yes, our product is safe for cats. It's an all-natural, simple formula made with eggs, sugar, and D-mannose (a natural sugar made from cranberries). That's it. No preservatives. No fillers. 100% natural.

How much sugar is in the product?

The sugar is added to protect the allergen-neutralizing proteins in the eggs through the freeze drying process. There is less than 1 gram of sugar in each jar. The sugar is added to protect the proteins in the egg from becoming de-natured during the freeze-drying process. 3% is the recommended sugar limit in a cat's daily diet. Our sugar amount is below this limit while still remaining effective.

What research have you done to formulate the supplement?

All of our research sources can be found on the ‘How it Works’ page here.

What safety and health measures are included in your manufacturing process?

Our farms and operations are based out of Dayton and Roanoke, Virginia. Both co-owners have professional experience in the food service industry and follow all Current Good Manufacturing Practice (CGMP), Virginia Department of Health (VDH), and Center for Disease Control (CDC) guidelines.
