Feline Hydrolyzed Protein HP Dry Cat Food
Verified Aug 30, 2026
This is a veterinary prescription dry diet for adult cats that uses hydrolyzed soy protein, which is broken down into very small pieces to reduce the chance of triggering food reactions and to support easy digestion. Brewers rice and beet pulp provide digestible carbohydrates and fiber, while added omega-3 fatty acids from fish oil help support skin and digestive health. It’s formulated as a complete and balanced maintenance diet for adult cats, often used under veterinary guidance for cats with

This is a therapeutic diet, formulated for a specific medical condition under veterinary direction. KibbleLab does not assign it a general wellness score, because a therapeutic diet's nutrient targets are set clinically, not by maintenance standards. Your veterinarian selects the right therapeutic diet for your pet.

Benefits the manufacturer highlights in its own product marketing. KibbleLab lists them for reference and does not verify these claims.KibbleLab Review
Strengths
- Uses hydrolyzed soy protein, which is designed to be less likely to trigger food allergies or sensitivities.
- Complete and balanced to AAFCO standards for adult maintenance, so it can be used as the sole diet for adult cats.
- Includes beet pulp, cellulose, and prebiotics to help support healthy stool quality and digestive flora.
- Provides omega-3 fatty acids from fish oil, which can support skin, coat, and gastrointestinal health.
Considerations
- Protein comes primarily from soy rather than animal muscle, which may not be ideal for very picky cats used to meat-based diets.
- This formula is for adult maintenance only, so it is not appropriate for kittens or pregnant or nursing queens.
- Contains chicken fat and fish oil, so it may not be suitable if your cat has known chicken or fish allergies in addition to other sensitivities.

Top 5 Ingredients Explained
01
Brewer's Rice
Brewer’s rice is a milling byproduct of rice processing made up of small broken white rice kernels commonly used in pet foods as a highly digestible carbohydrate source, filler and binder that provides readily available energy for dogs and cats while contributing little protein, fat or fiber. It is generally gentle on the stomach and cost‑effective, but diets using it must supply other ingredients for essential nutrients; pet owners should note its relatively high glycemic load (relevant for weight or diabetic pets), the potential for trace environmental contaminants associated with rice, and not confuse it with brewer’s yeast.
02
Hydrolyzed Soy Protein
Hydrolyzed soy protein is a processed plant protein broken into small peptides and amino acids and is used in pet foods as a digestible protein source and flavor enhancer, often in hypoallergenic or limited‑ingredient formulations. It can improve digestibility and may reduce allergic reactions for some animals, but it may still trigger soy‑sensitive pets, does not supply certain nutrients cats need from animal proteins (e.g., taurine), and formulations should be evaluated for added sodium or flavoring compounds.
03
Chicken Fat
Chicken fat is used in dog and cat foods as a concentrated energy and flavor source that supplies essential fatty acids (notably linoleic acid) and aids absorption of fat‑soluble vitamins, improving palatability and supporting skin and coat health. Because it is calorie‑dense, diets must account for added fat to prevent weight gain, and quality (proper rendering and antioxidant protection to prevent rancidity) is important; although fats are less commonly allergenic than proteins, pets with poultry sensitivities may still react in some cases.
04
Cellulose Powder
Cellulose powder is an insoluble, plant-derived fiber commonly used in pet foods as a bulking agent, binder and calorie-diluting texturizer to help control weight and improve stool formation; it is not digestible by dogs or cats and contributes negligible energy or vitamins. While it can aid stool consistency and manufacturing performance, cellulose is non‑fermentable so offers little prebiotic benefit, and high inclusions can reduce palatability or displace nutrients—formulations, especially for cats with lower fiber tolerance, should be balanced accordingly.
05
Natural Flavor
Natural flavor is used primarily as a palatability enhancer in pet foods to improve taste and aroma and is not intended to provide significant nutrients, typically coming from concentrated extracts of meat, poultry, plant, or fermentation sources. While it can increase acceptance in picky dogs and cats, manufacturers are not required to disclose specific sources so pets with known sensitivities or allergies may react, and presence of natural flavor should not be taken as a guarantee of overall product quality.
