Gastro cat: Assessment of the digestive tolerance in cats of a new diet based on insects as the protein source

This study was designed to evaluate the digestive tolerance of a new dry insect-based protein source diet in adult cats. (Poster Hypoallergy Cat Insect ISFM 2017)



Insects may be an alternative source of protein for animal nutrition and could represent a “novel” protein  source for managing adverse food reactions.  Publications describe the high-quality nutritional profile  of selected insect species, but there is little data on the  tolerance of insect-based diets. 


Animals, materials and methods

Twenty-three healthy adult client-owned cats were  recruited and monitored for 28 days. After a 4-day diet  transition, they were fed exclusively with the new diet (Table 1). This diet was formulated to meet FEDIAF  requirements for adult cats and was characterized by  mealworm (Tenebrio molitor larvae) as the protein source. Owners filled in online questionnaires on D0  (basal assessment with usual diets), D7, D14 and D28.  To evaluate tolerance of the diet, 4 parameters were  assessed (Table 2). Owners also evaluated coat  condition and palatability on D28. Wilcoxon signed rank and Mc Nemar’s tests were used to compare results,  with a 5% significance level.

The tolerance of the test diet was high, with no  significant changes vs usual diets. Mean faecal scores  varied from 2.3±0.5 on D0 to 2.2±0.4 on D28 and  none of the cats developed diarrhoea (highest scores:  3.5 in 2 cats on D7). Table 3 shows percentages of  normal cats on D0 and D28 for each digestive parameter. At the end of the trial, palatability was  described as good or very good by 74% of owners.  Coat condition was unchanged, improved or degraded  in 70, 26 and 4% of cats respectively.

Gastro cat: Assessment of a new high protein – low carbohydrate diet in cats with chronic gastrointestinal disease

The objective of this study was to evaluate the efficacy of a new dry high protein - low carbohydrate (HP-LC) diet intended for the management of chronic maldigestion-malabsorption in cats. (Poster Gastro Cat ISFM 2016)

Gastro cat: Assessment of a New High Protein - Low Carbohydrate - High Fat Diet in Cats with Chronic Gastrointestinal Disease Vol. 1 No. 1: 4

Dietary therapy is a major component in the management of most gastrointestinal disorders. The objective of this study was to evaluate the efficacy of a new dry high protein – low carbohydrate – high fat diet intended for the management of chronic maldigestion-malabsorption in cats. Forty-seven client-owned cats with chronic gastrointestinal diseases were recruited. During the first month (M1) of follow-up, they were fed exclusively the test diet (Virbac VETERINARY® HPM Digestive Support Cat). During the second month (M2), they were fed again their usual dry diet. If medical treatment became necessary during the study, the cat was excluded. To describe the clinical status, the 5 following digestive parameters were assessed 6 times, at inclusion, then each week of M1, and finally at the end of M2: frequency of defecation, faeces quantity, faecal score, faeces odour, and frequency of flatulence. Forty-four cats completed the study. The test diet resulted in significant improvement in all parameters. After 1 month fed the test diet, 72% of cats were completely cured (all parameters normal), 26% were partially improved, and only 2% were unchanged. At the end of M2, 61% of cats had minimum 1 parameter degraded again. These results confirm the clinical efficacy of the new highly digestible high protein – low carbohydrate – high fat diet for chronic gastrointestinal disease management and recurrence prevention in cats
