Virbac Adult Neutered

Virbac HPM Adult Neutered

Neutering is the single most impactful metabolic event in a domestic cat's life — and most cat foods completely ignore it. Virbac HPM Adult Neutered is built entirely around the metabolic reality of the neutered cat: reduced energy expenditure, elevated appetite drive, lost hormonal weight regulation, and elevated obesity risk that conventional adult formulas were never designed to address. This is the HPM formula developed exclusively for neutered cats — high protein to support satiety and lean muscle, low carbohydrate to eliminate the insulin-driven fat accumulation that plagues neutered adults, and precisely controlled minerals for the urinary health that neutered indoor cats require daily. Available in 400g  for first-time buyers and 1.5kg for established use.

Why Virbac HPM Adult Neutered Is the Best Choice for Your Neutered Cat

• Formulated Exclusively for Neutered Cats — Not a general adult formula with a "suitable for neutered" note — a formula whose entire macronutrient profile, caloric density, and nutritional architecture is designed around the specific metabolic changes that neutering produces.
• High Protein for Satiety & Muscle Maintenance — Elevated protein drives satiety through multiple hormonal pathways (PYY, GLP-1, CCK) — reducing the persistent hunger that neutered cats experience and preventing the muscle-wasting sarcopenic obesity that develops when caloric restriction reduces protein intake below maintenance requirements.
• Low Carbohydrate — Eliminating the Obesity Driver — The low-carb profile removes the postprandial insulin spikes that drive fat deposition in neutered cats — the metabolic mechanism responsible for the rapid weight gain that affects the majority of neutered cats within 1–2 years of surgery.
• Controlled Caloric Density — Calibrated to the reduced maintenance energy requirements of neutered cats — providing complete nutrition at the caloric level appropriate for a neutered adult without the caloric surplus that causes weight gain on standard adult formulas.
• Urinary Health Support — The high protein content naturally acidifies urine into the pH range where struvite crystals cannot form, combined with controlled mineral levels — addressing the elevated urinary risk that neutered indoor male cats in particular face.
• Two Sizes — Maximum Flexibility — 400g for trying HPM for the first time or for very small cats; 1.5kg for committed daily feeding with better per-gram value.
• Virbac Veterinary Nutritional Science — Developed by the same veterinary pharmaceutical company behind Cortavance and Pronefra — applying pharmaceutical-grade scientific rigor to nutritional formulation.

Product Details & Features

The Neutered Cat Metabolic Problem — In Detail — Within 48 hours of ovariohysterectomy (female) or orchiectomy (male), significant hormonal changes begin reshaping feline metabolism. Estrogen and testosterone regulate leptin sensitivity (the satiety hormone), basal metabolic rate, and fat distribution patterns. Their removal produces: a 20–30% reduction in basal metabolic rate, a 25–50% increase in food intake motivation (documented in multiple studies), and a loss of the hormonal appetite ceiling that normally prevents overconsumption. The result is a cat that wants significantly more food than before neutering, burns significantly fewer calories than before, and has lost the hormonal mechanisms that would normally regulate body weight. On a conventional adult dry food — formulated for the intact adult metabolism — this cat will gain weight consistently and progressively.

Why Conventional "Light" Formulas Fail Neutered Cats — The standard industry response to neutered cat obesity risk is "light" formulas — reduced-calorie versions of standard adult food achieved by lowering fat content and increasing fiber or carbohydrate content. The problem: reduced-fat, high-fiber/carb light formulas produce reduced satiety (fat and protein drive satiety; fiber and carbs do not, in cats), reduced palatability (cats find high-fiber, low-fat diets less appealing), and no improvement in the metabolic mechanisms driving obesity. A neutered cat on a light formula may receive fewer calories — but will be hungrier, less satisfied, and more likely to show food-seeking behavior. HPM's high-protein, low-carb approach produces genuine satiety at appropriate caloric levels — the metabolically correct solution.

High Protein Satiety — The Clinical Mechanism — Protein digestion triggers the release of multiple satiety-inducing gut hormones: peptide YY (PYY) from the ileum, glucagon-like peptide-1 (GLP-1) from the distal intestine, and cholecystokinin (CCK) from the proximal intestine. These hormones signal satiety to the hypothalamus, reducing appetite and food-seeking behavior. High-protein diets produce stronger and more sustained satiety hormone responses than equivalent-calorie high-carbohydrate diets — a documented effect across both human and companion animal nutrition research. For neutered cats whose satiety signaling is compromised by loss of estrogen/testosterone, the augmented satiety from high-protein feeding partially compensates for the lost hormonal satiety mechanisms.

Lean Muscle Preservation — The Sarcopenia Risk — The obesity that develops in neutered cats is characteristically sarcopenic — fat mass increases while lean muscle mass decreases concurrently. This pattern is driven by the combination of reduced exercise (indoor cats), reduced anabolic hormonal stimulation (testosterone and estrogen have muscle-preserving effects), and the inadequate protein content of many commercial adult formulas. Sarcopenic obesity produces worse metabolic outcomes than simple obesity — reduced physical capacity, worse insulin sensitivity, and poorer long-term health outcomes. HPM's high protein content provides the substrate for continuous muscle protein synthesis, directly counteracting the sarcopenic component of neutered cat weight change.

Urinary Health in Neutered Male Cats — The Critical Risk — Neutered male cats have the narrowest urethral diameter in companion animal medicine — and urethral obstruction, the life-threatening endpoint of severe FLUTD, occurs almost exclusively in this population. The combination of reduced activity, indoor lifestyle, stress, and inadequate dietary mineral management creates the conditions for crystal formation and obstruction. HPM's high protein (natural urine acidification) and controlled mineral content provide daily dietary urinary protection — the preventive nutrition that reduces obstruction risk as a background feature of every feeding.

The Formula Your Neutered Cat's Metabolism Has Been Waiting For

The moment your cat was neutered, their nutritional requirements changed fundamentally — and most cat foods on the market were not updated to reflect that change. Virbac HPM Adult Neutered was. High protein for the satiety your cat's compromised hormonal appetite regulation can no longer provide. Low carbohydrate for the insulin management your cat's altered metabolism requires. Controlled calories for the energy balance that prevents the weight gain that most neutered cats suffer. This is not a marginal improvement over conventional neutered cat food — it is a nutritionally different category of feeding, built on veterinary understanding of what neutering actually does to a cat.
