Sourcing & Provenance: The SiarFrozen Quality Standard

At SiarFrozen, we don't settle for "standard" pet food ingredients. We partner with Kiezebrink, a globally recognized leader in animal nutrition that supplies top-tier zoos, bird-of-prey centers, and wildlife parks across Europe. When you feed SiarFrozen, your pet is eating the same high-specification diet trusted by professional conservationists and nutritionists.

1. Professional-Grade Integrity

Kiezebrink’s expertise in feeding exotic animals means our products are held to clinical standards. We utilize a "nature-first" philosophy, sourcing raw materials that mirror the diet an animal would consume in its natural habitat.

  • Human-Grade Quality: We prioritize high-quality by-products and raw materials that meet strict safety requirements.
  • Biologically Appropriate: Every ingredient is chosen to support natural behavior, digestive health, and longevity.
  • No Hidden Fillers: Our products are free from the grains, soy, and artificial additives found in processed kibble.

2. Industry-Leading Accreditations

Authority isn't just claimed—it's verified. Through our supply chain, SiarFrozen products are backed by the most rigorous certifications in the UK:

  • DEFRA Approved: Our sourcing and handling processes meet the stringent requirements of the Department for Environment, Food & Rural Affairs.
  • UK Pet Food Members: Kiezebrink adheres to the "Feed Raw Right" initiative, ensuring responsible and safe raw feeding practices.
  • Transparency & Testing: Every batch is subject to microbiological testing to ensure it is free from pathogens, providing peace of mind for your home environment.

3. The Ethical Cold Chain

We believe that quality is preserved, not manufactured. To lock in the natural enzymes and vitamins, we utilize a strictly monitored cold chain.

  • Flash-Frozen Freshness: By freezing our products immediately at the point of production, we eliminate the need for chemical preservatives.
  • Sustainable Sourcing: We focus on reducing waste by repurposing high-quality materials into nutrient-dense food, contributing to a circular and sustainable food system.
  • Zoo-Level Nutrition: Because we supply the same products to zoological institutions, the nutritional analysis is precise, consistent, and scientifically grounded.
