The objectives of this study were to determine differences in apparent total tract energy and macronutrient digestibility, fecal and urine characteristics, and serum chemistry of domestic cats fed raw and cooked meat-based diets and extruded diet. Nine adult female domestic shorthair cats were utilized in a replicated 3 × 3 Latin square design. Dietary treatments included a high-protein extruded diet (EX; 57% CP), a raw beef-based diet (RB; 53% CP), and a cooked beef-based diet (CB; 52% CP…

Apparent Total Tract Macronutrient Digestibility, Serum Chemistry, Urinalysis, and Fecal Characteristics, Metabolites and Microbiota of Adult Dogs Fed Extruded, Mildly Cooked, and Raw Diets.
TLDR
The lightly cooked and raw diets tested were highly palatable, highly digestible, reduced blood triglycerides, maintained fecal quality and serum chemistry, and modified the fecal microbial community of healthy adult dogs.
Apparent total tract energy and macronutrient digestibility of one- to three-day-old, adult ground, extruded, and canned chicken-based diets in domestic cats (Felis silvestris catus).
TLDR
The data indicate that the whole prey tested herein maintained short-term health and are adequately digestible for use in companion animal diets, which may be different in terms of macronutrient, energy, and moisture profiles and nutrient digestibility.
Apparent total tract digestibility, fecal characteristics, and blood parameters of healthy adult dogs fed high-fat diets
TLDR
Increased dietary fat improved apparent total tract digestibility, did not alter fecal characteristics, and maintained the health status of all dogs.
Apparent nutrient digestibility of two raw diets in domestic kittens
TLDR
Higher dry matter, organic matter and protein digestibility was seen in two commercial raw diets compared with a heat-processed diet, and this difference resulted in significantly less fecal matter.
Apparent total tract macronutrient and energy digestibility of 1- to- 3-day-old whole chicks, adult ground chicken, and extruded and canned chicken-based diets in African wildcats (Felis silvestris lybica).
TLDR
Evaluated whole prey diets met macronutrient requirements for domestic cats; however, they were below recommendations in some minerals and tested positive for potentially pathogenic microorganisms (Salmonella, E. coli spp.).
Effects of inulin or yeast cell wall extract on nutrient digestibility and fecal fermentative end-product concentrations of healthy adult dogs fed raw diets
TLDR
The results agree with previous feline studies, demonstrating a high nutrient digestibility of raw diets in dogs, and Inulin and YCW inclusion in raw meat-based diets had similar effects on large intestinal fermentation as extruded diets containing inulin andYCW.
Influence of dietary fiber type and amount on energy and nutrient digestibility, fecal characteristics, and fecal fermentative end-product concentrations in captive exotic felids fed a raw beef-based diet.
TLDR
Data indicate that the optimum fiber type and concentration for inclusion in captive exotic felid diets is likely a combination of fermentable and nonfermentable fibers, with the optimal fiber blend being dependent on species.
Effects of inulin or yeast cell-wall extract on nutrient digestibility, fecal fermentative end-product concentrations, and blood metabolite concentrations in adult dogs fed raw meat-based diets.
TLDR
Results suggested the raw meat-based diets evaluated were highly digestible in dogs and the increase in fecal short-chain fatty acid concentrations achieved when inulin and YCW extract were included may be beneficial to canine health.
Digestibility Is Similar between Commercial Diets That Provide Ingredients with Different Perceived Glycemic Responses and the Inaccuracy of Using the Modified Atwater Calculation to Calculate Metabolizable Energy
TLDR
The modified Atwater equation does not accurately determine the metabolizable energy of high quality feline diets, and further research should focus on understanding carbohydrate metabolism in cats, and establishing an equation that accurately predicts the metabolisable energy of f cat diets.
Addition of plant dietary fibre to a raw red meat high protein, high fat diet, alters the faecal bacteriome and organic acid profiles of the domestic cat (Felis catus)
TLDR
It is shown that diets of different macronutrient proportions can strongly influence the faecal microbiome composition and metabolism, as shown by altered organic acid concentrations andFaecal pH, in the domestic cat.

Evaluation of nutrient digestibility and fecal characteristics of exotic felids fed horse- or beef-based diets: use of the domestic cat as a model for exotic felids.
TLDR
The results suggest that the domestic cat serves as an appropriate model for large exotic felid species, but differences among the species exist, and decreased nutrient digestibility by tigers and jaguars should be considered when developing feeding recommendations for these species based on domestic cat data.
Nutrient digestibility and fecal characteristics are different among captive exotic felids fed a beef-based raw diet.
TLDR
Differences in fat and digestible energy suggest that species should be considered when determining caloric needs of exotic felids, and beef-based raw diet was highly digestible.
Influence of feeding raw or extruded feline diets on nutrient digestibility and nitrogen metabolism of African wildcats (Felis lybica).
TLDR
Owing to lack of differences, data indicate that African wildcats can readily utilize a high protein extruded kibble diet, and may be able to replace a commercial raw meat diet.
Effects of six carbohydrate sources on diet digestibility and postprandial glucose and insulin responses in cats.
TLDR
The data suggest that starch has less of an effect on the cat postprandial glucose and insulin responses than on those of dogs and humans, and this can be explained by the metabolic peculiarities of felines, which may slow and prolong starch digestion and absorption, leading to the delayed, less pronounced effects on their blood responses.
Effect of different fibre types on the digestibility of nutrients in cats.
TLDR
It can be concluded, that not only the absolute fibre content of the food but also the type of fibre must be taken into account when evaluating its possible role as a component of weight loss products.
Comparison of feed preference and digestion of three different commercial diets for cats and ferrets.
TLDR
The ferret cannot be used as a model animal for cats either for preference or digestibility studies, as the data indicates that cats and ferrets have a clear preference for diets of higher fat content.
In utero and postnatal exposure to a high-protein or high-carbohydrate diet leads to differences in adipose tissue mRNA expression and blood metabolites in kittens
TLDR
The present results demonstrate some of the changes in blood metabolites and hormones, physical activity and mRNA abundance that occur with feeding high protein levels to kittens.
Use of a raw meat-based diet or a dry kibble diet for sand cats (Felis margarita).
TLDR
The results indicate that diets formulated for small captive exotic felid species should be evaluated with respect to diet type and nutrient utilization.
Influence of cellulose fibre length on faecal quality, mineral excretion and nutrient digestibility in cat.
TLDR
Results suggest a remarkable likeness between cats and dogs with regard to the digestive physiology of major minerals.
IRRADIATION OF DIETS FED TO CAPTIVE EXOTIC FELIDS: MICROBIAL DESTRUCTION, CONSUMPTION, AND FECAL CONSISTENCY
TLDR
Data indicate that irradiation of frozen horse meat–based diets result in microbial destruction in these products but that product storage time between irradiation and sampling may also affect microbial reduction, and irradiation would be an appropriate method for reducing potentially pathologic bacteria in raw meat fed to exotic cats.
