Feline kidney formula

EmerAid® Intensive Care™ HDN™ Kidney Feline

or “Highly Digestible Nutrition” is a semi-elemental therapeutic diet scientifically designed to meet the needs of the feline with Chronic Kidney Disease. Developed by veterinarians and nutritionists, this formula provides controlled levels of phosphorous and low sodium, easily absorbable amino acids, increased potassium, l-carnitine, and omega-3 fatty acids. Intensive Care HDN Kidney Feline is designed to control clinical signs of uremia and minimize progression of kidney disease while sustaining lean muscle mass.

  • Highest kcal/ml for feline kidney disease: 1.45 kcal/ml
  • Highly digestible essential amino acids like L-carnitine to support lean muscle mass and combat cachexia
  • Controlled phosphorous levels help delay the progression of CKD
  • Omega 3 fatty acids – EPA & DHA – aid in slowing CKD progression Antioxidants to minimize oxidative stress
  • Semi-elemental diet = Fastest nutrient absorption
  • Easy to administer through a tube as small as 5Fr.
  • 30-day shelf life after opening
  • Available in 100-gram and 400-gram pouches

Features & Benefits

  • High energy (1.45-2.81 kcal/ml ME)
  • 1 month shelf life after opening
  • Goes through tubes as small as 5 Fr without clogging
  • Excellent for bolus tube feeding or syringe feeding
  • Controlled phosphorous levels help delay the progression of CKD
  • High quality, highly digestible essential amino acids like L-carnitine to support lean muscle mass and combat cachexia
  • Purified fiber sources to maintain intestinal motility and commensal microflora
  • Cellulose serves as a source of insoluble fiber and acts as a prebiotic
  • Essential amino acids to meet the needs of the metabolically stressed patient
  • Enriched in branched chain amino acids to benefit muscle synthesis and repair
  • Hydrolyzed soy protein minimizes gastrointestinal hypersensitivity. These highly digestible macronutrients prevent and manage osmotic diarrhea, as is associated with completely elemental diets
  • Glutamine and arginine support immunity and antioxidant systems
  • Enterocyte health maintained and supported allowing for the maximum absorbable nutrition in the gastrointestinal tract
  • Omega 3 fatty acids – EPA & DHA – aid in slowing CKD progression, modulate the inflammatory response and aid in tissue synthesis
  • Synergistic antioxidants vitamin E, vitamin C, zinc and taurine to defend against oxidative stress
  • A-casozepine or dehydrated casein supports digestion of fats and tissue synthesis while providing anxiolytic properties
  • L-tryptophan, a precursor for the synthesis of serotonin to reduce stress
  • Dietary nucleotides provide RNA and DNA precursors to support the immune system, nourish the gastrointestinal tract, and assist in weight gain
  • Corn syrup solids essential for acute carbohydrate needs associated with debilitation. Partially hydrolyzed starch supplies glucose, disaccharides, and oligosaccharides, which avoids the osmotic problems associated with feeding only glucose
  • Balanced electrolytes
  • Stabilized vitamins and chelated minerals
  • Neutral pH
  • Free of artificial colors and preservatives
  • Naturally preserved with mixed tocopherols and citric acid

Storage, Handling & Expiration Date

Store in a cool, dry space. Refrigerate after opening, and use within 1 month of opening. The shelf life of an unopened bag is indicated by the “Best Before” date, which is 18 months from the manufacturing date.

Feeding Recommendations

Download Feeding Recommendations (PDF)

Begin with 25% to 33% of resting energy requirements and gradually increase the volume and number of feedings based on patient condition. A volume of 5-10 ml/kg/feeding is generally well tolerated via esophagostomy or gastric tube. Resting energy requirements can be calculated using the following equation in most cats: [BW(kg) x 30] + 70. For cats weighing <2 kg, use [70 x BW(kg)0.75].

This product is to be used only under the supervision of a veterinarian. EmerAid Intensive Care HDN Kidney Feline is intended for intermittent or supplemental use only.
