One Brand, One Standard of Care

Cassiel Pet brings our research, products, educational work, quality standards, global channels and customer care together under one brand. Different legal, payment, privacy, fulfillment and regional functions may be handled by the appropriate operating entities and service partners, while the products and the standards behind them remain recognizably Cassiel Pet.

Our policies identify the responsible parties where legal, payment, privacy, fulfillment or regional details matter. Here, the focus stays on the Cassiel Pet story: why the brand exists, who contributes to its work and which standards guide the products.

For the applicable legal and service terms, see the Terms of Service, Privacy Policy, Shipping Policy and Refund & Return Policy.

Our Story — It Started With a Cat Who Wouldn't Stop Scratching

It started with a cat who wouldn't stop scratching.

Our founder — a lifelong pet parent — had tried everything on the market. Shampoos that promised relief and made things worse. Sprays with ingredients she couldn't pronounce. Vet bills that kept climbing with no lasting solution in sight.

She didn't find a brand that met her standards.

So she built one.

Cassiel Pet was founded on a single belief: pets are family, and family deserves real care — not marketing promises dressed up in scientific-sounding labels.

Cassiel Pet® Official Brand Protection & Authenticity Verification

Cassiel Pet® is a registered pet care brand protected by trademark registration in the United States.

Our trademark registration represents the official identity of Cassiel Pet and protects our brand name, logo, and product recognition across global markets.

Cassiel Pet® United States Trademark Registration Certificate — Official Brand Identity Protection

As Cassiel Pet continues to expand internationally, unauthorized sellers and third-party websites may attempt to use our brand name without official authorization.

Products purchased from unofficial websites, unknown marketplaces, or unauthorized sellers may not be genuine Cassiel Pet products. Their manufacturing sources, product authenticity, storage conditions, and quality standards cannot be verified by our team.

To ensure authentic Cassiel Pet products, official customer support and verified quality standards, customers should use our official website or a verified Cassiel Pet marketplace storefront:

Cassiel Pet Official Website: https://www.cassielpet.com

We believe every pet parent deserves complete transparency — not only about what goes into our products, but also where those products come from.

We partnered with veterinary specialists and university researchers, went back to the science, and built a product line from the ground up — one where every ingredient earns its place, with research input, manufacturing controls and product-specific evaluation guiding the formulas before they reach pet parents.

Today, Cassiel Pet is trusted by pet parents across the United States, Mexico, the Philippines, Thailand, Malaysia, and beyond, with customers discovering our products through our official website and leading global e-commerce platforms.

The mission has never changed: providing safe, effective, and affordable pet healthcare solutions that support the everyday wellness of dogs and cats.

From veterinary manufacturing standards to everyday pet care solutions, Cassiel Pet continues to focus on one goal: helping pet parents make more informed choices and provide better care for the animals they love.

The Problem We Set Out to Solve

Walk into any pet store or scroll through any online marketplace, and you'll find hundreds of products claiming to solve your pet's skin problems. Most of them share a common flaw: they treat the surface, not the source.

A shampoo that masks the itch without addressing the bacterial or fungal infection causing it. A spray that smells pleasant but contains no clinically active ingredients. A "natural" formula that's 95% water and marketing language.

Pet parents — especially those with dogs or cats dealing with chronic skin conditions, parasites, ringworm, or post-surgical recovery — deserve better than that. They deserve products built the same way human pharmaceutical products are built: with regulated active ingredients, manufacturing oversight, independent testing, and honest claims.

That is the standard Cassiel Pet holds itself to. Not because it's easy — it's considerably harder and more expensive than selling a cosmetic-grade product — but because your pet's health demands it.

University-Backed Research

We don't use the phrase "vet-formulated" loosely.

Cassiel Pet operates in active partnership with the School of Life Sciences & Food Engineering at Anqing Normal University (安庆师范大学生命科学与食品工程学院), where we co-founded the:

"Anqing Normal University × Cassiel Pet Joint Research Laboratory for Pet Health Biologics" (安庆师范大学 × Cassiel Pet 宠物健康生物制剂联合研究室)

This university-industry collaboration means our formulas are developed alongside active, publishing researchers — not created in isolation and handed to a manufacturer. Current biological research informs relevant product-development questions, while the evidence, testing and regulatory path appropriate to each individual product determine the claims and directions used for that product.

Research and Veterinary Team

Lead Research Specialist — Dr. Liu Xiqian (刘茜倩)

Current Position: Faculty, Department of Biotechnology, School of Life Sciences & Food Engineering, Anqing Normal University Doctoral Training: Shanghai Jiao Tong University (上海交通大学) — Ecology (Animal Science & Engineering) Research Focus: Animal virus molecular immunology; microbiology; pathogen-host interaction mechanisms; antiviral innate immunity

Dr. Liu is a doctoral graduate of Shanghai Jiao Tong University — consistently ranked among China's top five research universities — where she spent five years conducting advanced research in animal virus biology and molecular immunology. Her academic work spans H1N1 influenza virus biology, porcine coronavirus vaccine development, and the molecular mechanisms by which animal pathogens evade and manipulate host immune responses.

The expertise of Dr. Liu in animal immunity, microbiology and pathogen–host interactions gives Cassiel Pet access to scientific thinking that most consumer pet-care brands cannot identify by name. Her research background contributes to relevant research questions, evidence review and educational accuracy across the pet-health work of the brand.

Dr. Liu currently teaches Microbiology at Anqing Normal University and has participated in multiple projects funded through the National Natural Science Foundation of China (NSFC), a major national research funding program.

GMP-Certified Veterinary Manufacturing

Cassiel Pet products are supported by a documented veterinary pharmaceutical manufacturing system operating under veterinary production licensing and GMP controls. These controls cover areas such as raw-material management, manufacturing consistency, clean production environments, quality inspection, packaging and batch traceability.

Manufacturer names, licence numbers, certificate images, validity periods and document scope are published on our Certifications & Credentials page. Keeping those records together makes them easier to read and verify without turning the brand story into a list of registration details.

The records published online are representative examples from a broader compliance portfolio. Most Cassiel Pet core products have obtained the certificates, registrations, approvals or compliance records applicable to their category and target market. The Certifications & Credentials page shows selected evidence while protecting the complete commercial and regulatory file library of the brand.

U.S. EPA Producing-Establishment Record

Cassiel Pet publishes the EPA producing-establishment record associated with Establishment No. 106193-CHN-1. The 2026 record identifies Avermectin Pour-on Solution in the product information and connects the named parasite-care formulation with a reported producing location.

An establishment number identifies the producing establishment; it is different from a product-specific EPA registration number. Explaining the distinction does not weaken the credential—it shows that Cassiel Pet understands and publishes the evidence according to its correct regulatory scope.

U.S. FDA Food Facility Record — Nutritional Product Traceability

Cassiel Pet publishes the food-facility record associated with Registration No. 19718602452 and the documented categories that include pet food, pet fish oil and Cassiel Pet nutritional gel. This record supports supply-chain identity and traceability for the applicable nutritional-product categories.

FDA food-facility registration is not blanket approval of every finished Cassiel Pet product. The full document image, reporting period and scope explanation are available on the Certifications & Credentials page.

China National Veterinary Drug Approval Records (中国国家兽药产品批准文号)

Several core Cassiel Pet products carry individual National Veterinary Drug Approval Numbers (兽药产品批准文号) — government-issued registrations confirming each product's safety and efficacy have been independently reviewed and approved by China's national regulatory authority.

These are not supplement-grade products with unverified claims. They are regulated veterinary pharmaceutical products — the same standard of oversight applied to medications dispensed in licensed veterinary clinics.

International Customer Community

We didn't build our reputation on advertising spend. We built it on results — verified by millions of real pet parents across three continents.

We currently ship to: United States 🇺🇸 · Mexico 🇲🇽 · Philippines 🇵🇭 · Thailand 🇹🇭 · Malaysia 🇲🇾 · and expanding.

Cassiel Pet Across Global Marketplaces

• CASSIEL PETMALL on Shopee Philippines displayed a 4.9 store rating and approximately 274,000 followers in a public storefront snapshot reviewed in August 2026.
• Cassiel Pet World on TikTok Shop US and other Cassiel Pet storefronts show substantial public sold counters, reviews and engagement.
• Cassiel Pet on Lazada Philippines adds an established regional marketplace presence.

A single storefront counter reflects only that platform, listing or reporting period; it is not the Cassiel Pet lifetime total. Based on Cassiel Pet first-party review and repeat-purchase records consolidated through August 2026 across direct, marketplace and social-commerce channels, the brand also reports more than 50,000 five-star reviews, an average rating of approximately 4.6/5 and a repeat-purchase rate above 63%. Marketplace display rules and reporting windows can differ by channel.

These direct and public signals explain why Cassiel Pet can accurately describe the brand as trusted by millions across multiple regions and commerce channels.

🤝 Animal Rescue and Community Support

Cassiel Pet is more than a product brand. It is a community built around the belief that every animal deserves care — including those who don't yet have a family.

We maintain active partnerships with animal rescue organizations and charitable foundations globally, donating medical supplies and skincare products to shelters and stray animal care programs on an ongoing basis. The growth of Cassiel Pet helps sustain continuing product and medical-supply support for animals that need care.

Because if we truly believe pets are family, that belief cannot stop at the animals already in loving homes.

Pets Come First

At Cassiel Pet, this has never been purely a business decision.

We know the 2am worry when your dog won't stop scratching. The helplessness of watching your cat lick the same raw patch for the third week in a row. The frustration of spending money on products that don't work — and the quiet guilt of not knowing what will.

We built Cassiel Pet because we have been exactly where you are. And we refused to accept that the only options were expensive clinic visits or ineffective over-the-counter products with no real science behind them.

Every formula we develop starts with one question: Would we use this on our own pets?

If the answer isn't an immediate yes, it doesn't ship.

Frequently Asked Questions About Cassiel Pet

Q: Is Cassiel Pet just another "natural" pet brand?

No. While we use plant-based ingredients in many formulations, Cassiel Pet distinguishes itself through university-backed research, GMP-certified pharmaceutical manufacturing, and government-approved veterinary drug registrations. Several of our core products are regulated pharmaceutical products — not cosmetic or supplement-grade items.

Q: How can I identify the official Cassiel Pet website?

Cassielpet.com is the official direct-to-consumer website operated by the brand team. Cassiel Pet also operates or authorises storefronts on selected marketplaces. Customers should verify the seller identity and use the official website or the marketplace channels listed on this page.

Q: Who actually formulates your products?

Our formulas are developed in active collaboration with Dr. Liu Xiqian (doctoral graduate of Shanghai Jiao Tong University, faculty at Anqing Normal University) and Associate Professor Liu Zhigang, a veteran veterinary clinical specialist. This is a working research partnership — not an advisory relationship in name only.

Q: Are your products safe for both dogs and cats?

Cassiel Pet serves both dog and cat care categories, but suitability depends on the exact formula. Follow the species, age, weight, dosage and warning information on the specific product label and product page; do not transfer directions from one SKU to another.

Cassiel Pet products are supported by documented veterinary manufacturing and GMP controls. The exact manufacturing records, license number, certificate image and applicable scope are published on the Certifications & Credentials page.

Q: Can I verify your product approval numbers?
