When your cat eats the yeast, an unpleasant odour forms inside the animal's body and repels fleas.
Source of B Vitamins
Brewer's yeast provides cats a good source of B vitamins. According to the University of Maryland Medical Center, "the B-complex vitamins in brewer's yeast include B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B9 (folic acid) and H or B7 (biotin)." B vitamin complexes break down fats, proteins and carbohydrates, which provide your cat energy. In addition, B vitamins can support your cat's nervous system, aid digestion and keep his coat, eyes, skin and liver in healthy condition.

Possibly Lowers Cholesterol
Brewer's yeast possibly lowers bad cholesterol in cats. According to the University of Maryland Medical Center, "[a] few studies suggest that brewer's yeast may help lower LDL ('bad') cholesterol levels in the blood and raise HDL ('good') cholesterol levels." However, researchers are unsure if the effect on cat's cholesterol is from the chromium that is present in brewer's yeast or from another substance.
