Cats are strict carnivores and in the wild rely on a diet solely based on animal tissues to meet their specific and unique nutritional requirements. Although the feeding ecology of cats in the wild has been well documented in the literature, there is no information on the precise nutrient profile to which the cat's metabolism has adapted. The present study(More)
With domestication and urbanisation, cats have transformed from being hunting animals that eat protein-rich prey into more sedentary animals that eat a carbohydrate-rich diet. It was hypothesised that a high intake of dry cat food and a lack of physical activity may play a role in the development of feline type 2 diabetes mellitus. Information on dietary(More)
The prevalence of calcium oxalate (CaOx) uroliths detected in cats with lower urinary tract disease has shown a sharp increase over the last decades with a concomitant reciprocal decrease in the occurrence of struvite (magnesium ammonium phosphate) uroliths. CaOx stone-preventative diets are available nowadays, but seem to be marginally effective, as CaOx(More)
A retrospective study was carried out on the efficacy of seven commercial diets designed to be fed to cats with chronic renal failure. The median survival time of 175 cats that received conventional diets was seven months, whereas the median survival time of 146 cats given one of the seven diets was 16 months. The cats on the most effective of the diets had(More)
The question addressed was whether the fatty acid composition of plasma cholesteryl esters (CEs) in cats reflects the intake of fatty acids. Diets containing either fish oil or sunflower oil were fed to six healthy, adult cats in a cross-over trial. The dry cat foods contained approximately 18.5% crude fat, of which two-third was in the form of the variable(More)
The present study was carried out to ascertain whether linoleic acid intake and the content of this fatty acid in adipose tissue are correlated in cats. The linoleic acid intake, as estimated from a food intake questionnaire, was indeed correlated with the linoleic acid content of the abdominal body fat in 165 adult, female cats. A statistically significant(More)
A study was carried out to assess the qualitative risk of development of chronic renal failure (CRF) in young healthy, female cats as based on the content of arachidonic acid (AA) in plasma cholesteryl esters (CE) and eicosapentaenoic acid (EPA) in adipose tissue. It has been suggested that the content of AA in CE should be <10% of total fatty acids (TFA)(More)
The objective of this study was to compare renal diets for cats that are commercially available in The Netherlands. The diets were analysed and their composition compared with a guideline proposed by the authors. Special attention was paid to the fatty acid composition of the diets and the role of fatty acids in the progression of chronic renal failure. On(More)
Chronic renal failure (CRF) is a common clinical problem in cats, affecting up to 30% of all animals above 15 years of age.1 Affected cats have a poor prognosis because the renal dysfunction frequently progresses to end-stage renal failure.2 The pathogenesis of CRF in general is not yet fully understood, but in people risk factors such as systemic(More)
