Hydrolysed Cat Food for Digestive Care, Urinary Health & Coat and Hairball Control

Grain-Free Hydrolysed Cat Food for Sensitive & Sterilised Cats

Ultimate Plus Cat is a specialist range of grain-free hydrolysed cat food, developed for adult and sterilised cats that need more from their diet — whether that’s support for digestion, urinary health, skin condition or hairball management.

Every recipe uses our Freshtrusion HDP (Highly Digestible Protein) process to break proteins into short-chain peptides before your cat eats them — delivering proven 90–92% protein digestibility and a hypoallergenic formula gentle enough for daily, long-term feeding.

  • Formulated for a specific health condition

What is Hydrolysed Cat Food?

Hydrolysed cat food uses proteins that have been broken down into small peptide chains through a controlled enzymatic process — before the food ever reaches your cat’s bowl. These short-chain di- and tri-peptides are absorbed more efficiently than intact proteins, carry far lower allergenic potential, and place significantly less demand on your cat’s digestive system.

It is particularly beneficial for cats with food sensitivities, intolerances or suspected allergies, and for health conditions where digestibility and low antigen load matter — such as gastrointestinal disorders, urinary crystal formation or chronic skin reactions.

Why Choose Ultimate Plus Cat Hydrolysed Food?

Proven Digestibility — Beyond Industry Standards

Our Freshtrusion HDP process achieves up to 92% protein digestibility — far exceeding the FEDIAF 80% standard. In independent feeding trials, 90% of cats on our Urinary Care recipe achieved optimal urine pH, and 95% of owners in the Skin, Coat & Hairball Care trial reported visible coat improvement.

Condition-Specific Recipes — Not Generalised Nutrition

Each recipe is formulated to support a specific health goal — with ingredients chosen for their clinically supported role, not just nutritional completeness. Three different protein sources (turkey, chicken, salmon) mean each recipe is genuinely distinct in its mechanism of action.

No Prescription Required

Unlike pharmaceutical veterinary diets, all Ultimate Plus Cat recipes are complete everyday foods available without a prescription — ideal for cats with ongoing conditions that need dietary support without the cost or inconvenience of recurring vet prescriptions.

Our Three Hydrolysed Cat Food Recipes

Gastrointestinal & Digestive Care — Hydrolysed Turkey

Formulated with hydrolysed turkey peptides, collagen peptides for gut barrier integrity, and prebiotic FOS & MOS for a balanced microbiome. Independently verified at 92% protein digestibility. Ideal for cats with loose stools, food sensitivities or sensitive stomachs.

Urinary Health & Crystal Control — Hydrolysed Chicken + UriTract™

Combines hydrolysed chicken peptides with our exclusive UriTract™ blend — cranberry, camomile, rosehips, L-tryptophan and L-carnitine — to support optimal urine pH and discourage struvite and calcium oxalate crystal formation. In trials, 90% of cats achieved optimal urine pH. No prescription required.

Skin, Coat & Hairball Control — Hydrolysed Salmon + Four Omega Sources

Enriched with four targeted omega sources — salmon oil (EPA & DHA), soya oil (linoleic acid), dried algae (DHA) and borage oil (GLA) — to nourish skin and deliver a naturally glossy coat. Beet pulp and cellulose provide functional fibre for natural hairball passage. 95% of owners saw coat improvement in a 2025 feeding trial.

Hydrolysed Cat Food for Sterilised Cats

Sterilised cats have specific nutritional requirements that make them more susceptible to urinary crystals, weight gain, digestive sensitivity and reduced coat condition. All recipes in this range are formulated for both adult and sterilised cats — addressing these increased health risks through targeted nutrition, not just a generalised ‘sterilised cat’ label.

Is Hydrolysed Cat Food Better Than Regular Cat Food?

For cats with no health concerns, regular complete cat food is sufficient. But for cats with recurring digestive issues, food sensitivities, urinary problems or coat conditions, hydrolysed cat food addresses the root nutritional cause. The Freshtrusion HDP process makes protein inherently easier to digest and less likely to trigger immune responses — benefits that standard manufacturing cannot replicate.

  • Hypoallergenic — hydrolysed protein with very low antigenic potential
  • Complete and balanced — suitable for everyday, long-term feeding

Frequently Asked Questions: Hydrolysed Cat Food for Digestive Care, Urinary Health & Coat and Hairball Control

Quick answers to the most common questions.

What is hydrolysed cat food?
Hydrolysed cat food uses proteins broken down into tiny short-chain peptides through a controlled enzymatic process. These small fragments are absorbed more efficiently, carry very low allergenic potential, and are far gentler on the digestive system than intact proteins. This makes hydrolysed cat food the most effective dietary option for cats with food sensitivities, persistent digestive issues or skin conditions linked to dietary protein.
Does hydrolysed cat food help with urinary crystals in cats?
Yes. A hydrolysed cat food formulated with controlled magnesium and phosphorus levels and a pH-supporting mineral profile can help discourage the formation of struvite and calcium oxalate crystals — the two most common urinary conditions in cats. Our Urinary Health & Crystal Control recipe includes the exclusive UriTract™ blend, and in feeding trials 90% of cats achieved optimal urine pH.
Can I use hydrolysed cat food instead of a prescription urinary diet?
Our Ultimate Plus Cat range is not a veterinary prescription diet, but it is formulated to support urinary health through targeted nutritional balance — including controlled minerals and pH-supporting ingredients. It is a complete everyday food suitable for long-term feeding without a vet prescription. Always consult your vet if your cat has been diagnosed with a specific urinary condition.
What is the best cat food for cats with loose stools or sensitive stomachs?
For cats with loose stools, food sensitivities or sensitive stomachs, a hydrolysed grain-free cat food is generally the most effective dietary approach. Hydrolysed protein carries very low allergenic potential and is pre-digested into small peptides before eating, reducing the digestive workload and the risk of immune reactions. Our Gastrointestinal Digestive Care recipe achieves 92% protein digestibility — far above the FEDIAF 80% standard.
Does grain-free hydrolysed cat food help with hairballs?
Yes. Our Skin, Coat & Hairball Control recipe is specifically formulated with beet pulp and cellulose — two complementary natural fibre sources that support gut motility, helping ingested hair pass through the digestive tract naturally rather than forming hairballs. In a 2025 feeding trial, 95% of owners saw an improvement in their cat’s coat condition, and the functional fibre approach is more effective than lubricant-based hairball remedies for long-term control.
