Feline HDN

EmerAid® Intensive Care™ HDN™ Feline

“Highly Digestible Nutrition” is a semi-elemental therapeutic diet scientifically designed for the critically ill cat. Developed by an expert panel, including critical care veterinarians and nutritionists, this therapeutic diet is easily absorbed and highly digestible.

  • Available in 100-gram, 400-gram, and 2-kg pouches
  • Powder is easily mixed with water to create a formula that can pass through tubes as small as 5-French
  • When fed to growing or lactating animals, supplement the diet daily with 1% fish oil on a dry matter basis to ensure proper docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) levels
  • Meets AAFCO nutritional requirements for feline maintenance

How to Administer EmerAid Feline HDN

Indications & Contraindications

EmerAid® Intensive Care HDN Feline is designed for debilitated patients that require an easily absorbed and highly digestible diet. Use EmerAid® Intensive Care HDN Feline for nutritional support during:

  • Critical Illness
  • Post-operative period in debilitated patients
  • Malabsorption/maldigestion
  • Poor weight gain
  • Cachexia
  • Anorexia, inappetance
  • Acute kidney disease
  • Hepatic lipidosis
  • Infectious disease
  • Autoimmune disease
  • Peritonitis
  • Anemia
  • Convalescence


  • Advanced stages of chronic kidney disease
  • Hepatic encephalopathy

Features & Benefits

  • High energy (1.13-2.41 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
  • Appropriate low levels of carbohydrates and high levels of protein for the true carnivore
  • High quality, easily digestible forms of protein aid tissue synthesis and maintain lean body mass
  • 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 to 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
  • Meets AAFCO nutritional requirements for all life stages

Storage, Handling & Expiration Date

EmerAid® Intensive Care HDN Feline is a therapeutic product to be used under the supervision of a veterinarian. Begin with 25% to 30% of daily caloric requirements and gradually adjust 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. Calculate Resting Energy Requirement (RER) by using the following: RER = [70 x BW(kg)0.75].

When fed for longer than 1 month, supplement EmerAid® Intensive Care HDN Feline daily with 1% fish oil on a dry matter basis. When EmerAid HDN is fed to lactating animals longer than 1 week, it is recommended that the diet be supplemented daily with 1% fish oil (DMB). The NRC recommends a level of 0.025 g/1,000 kcal ME of a combination of DHA and EPA for both kittens and adult cats.

Kitten Feeding Recommendations

Kittens have relatively high energy requirements when compared to adult cats. EmerAid ® Intensive Care HDN Feline meets or exceeds requirements for all life stages with the one exception of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) levels. When EmerAid HDN is fed to growing animals longer than 1 week, it is recommended the diet be supplemented daily with 1% fish oil (DMB). The NRC recommends a level of 0.025 g/1,000 kcal ME of a combination of DHA and EPA for both kittens and adult cats.

Feedings are cautiously planned for every 4 to 6 hours in this patient. Dividing 97 ml by 4 gives us approximately 24 ml per feeding. Begin  with 30% to 50% of this estimated volume for the first feeding:  ~7 ml to 12 ml.


Evaluate the Patient’s Feeding Response

Did the patient accept this feeding well? Does the food appear to be tolerated by the patient’s GI tract?

If yes, increase the volume fed gradually over the course of two to three feedings. Frequency and volume should be adjusted based upon patient response, but a cautious plan could be:

First meal:1/3 of calculated energy requirements ~ 7 ml
Second meal:2/3 of calculated energy requirements ~ 14 ml
Third meal:3/3 of calculated energy requirements ~ 24 ml
If patient still tolerates the increase in frequency and in volume of EmerAid® Critical Care HDN Feline, continue feeding per below:
Daily meals:24 ml four times/day

Long-Term Feeding

Patients requiring long-term (4+ weeks) nutritional support may remain on EmerAid® Intensive Care HDN™. If the patient is able to tolerate more whole nutrients they may gradually be transitioned to EmerAid® HDN™ Sustain™ Recovery Nutrition, under the direction of a veterinarian. EmerAid® Sustain™ HDN™ Feline is indicated for patients recovering from a critical illness but are not ready for their normal diet.
