View Dental Care →Prescription hydrolysed diets — Hill's z/d, Royal Canin HP, Purina HA — are classified as complementary dietetic petfoods under UK animal feed legislation (Regulation 767/2009). They are licensed as therapeutic products and must be used under veterinary supervision.
Non-prescription hydrolysed cat food achieves the same core mechanism — breaking dietary protein into small, low-antigen peptides — but is formulated as a nutritionally complete everyday food, not a therapeutic diet. It requires no clinical authorisation and is suitable for long-term daily feeding.

Many owners make this switch for long-term maintenance once their cat is stable. Always consult your vet before changing your cat's diet if they have a diagnosed medical condition. Transition gradually over 7–14 days to avoid digestive upset during the changeover.
Yes. All Ultimate Plus Cat recipes are nutritionally complete and balanced for everyday, long-term feeding — unlike some therapeutic diets intended only for short-term management. They meet the nutritional standards required for a complete adult cat food under UK legislation.
Our Freshtrusion HDP process produces short-chain di- and tri-peptides — the same target size range as premium prescription products. Our Gastrointestinal Digestive Care recipe achieved 92% protein digestibility in an independent study at West Pomeranian University of Technology, Poland, significantly above the FEDIAF 80% benchmark. All recipes are formulated by trained pet nutritionists and approved by licensed veterinarians.
