Summary This study evaluated the effects of increasing concentrations spray‐dried yeast cell wall ( YCW ) in diets for healthy adult cats on apparent nutrient digestibility and bacterial composition fermentation products stool. Fourteen with an average weight 4.40 ± 1.05 kg age 6.2 0.54 years were used assigned to treatments unbalanced randomized block design (by experimental period) two blocks three or four per diet each block. Treatments included: control (0% ), 0.2% , 0.4% 0.6% totalling seven animals diet. We found that did not affect body weight, food intake, faecal production, score, pH urine output p > .05). Regarding bacteria, we observed a linear reduction Clostridium perfringens quadratic Escherichia coli increases Bifidobacterium spp. Lactobacillus < .05) inclusion . short‐chain fatty acid profile, butyrate, valerate, total biogenic amines, putrescine, cadaverine histamine increased linearly It was concluded cats, consumption modulates populations, presence beneficial bacteria some potentially pathogenic bacteria. modulated levels products. There increase coming from carbohydrate metabolism, important effect can benefit intestinal health cats. The also nitrogen compounds, which have yet been defined as deleterious beneficial. fermentability carbohydrates compounds may be associated. Therefore, cause rapid both classes by enhancing one class.
