Can Cats Eat Sourdough Bread?

Because sourdough bread contains more yeast than other kinds of bread, you have to be careful when it comes to its nutritive value and food value.

The sourdough bread you eat is a fermented product and contains more yeast than other kinds. The yeast in sourdough usually makes it rise and then ferments.

It might also contain yeast and lactobacillus cultures that are used in the fermentation process.

In fact, sourdough bread is often fermented for over a week before it is baked and ready to eat.

The yeast may react with the carbohydrates in sourdough bread to produce carbon dioxide, alcohols, and acids that give it a distinctive taste and smell. However, many cats have very sensitive taste-buds and sense of smell.

Cats cannot smell or taste yeast naturally, and even for those with highly sensitive nose and palates, they might have a hard time detecting the flavor of the sponge used for fermentation in sourdough bread.

The carbohydrates in sourdough bread are the main source of energy for the body, and cats need carbohydrates in order to fuel their nervous system and fuel muscles for exercise.
