Cats can eat bread occasionally, but not too much. Bread contains a lot of starch and sugar, which cats' digestive systems cannot effectively digest. Therefore, long-term consumption can put stress on a cat's digestive system and even lead to gastrointestinal problems.

Meanwhile, the sugar and oil in bread can also cause cats to become obese, trigger allergic reactions, or dental problems. It is recommended to give bread to cats occasionally as a treat, and their daily diet should still consist mainly of cat food or suitable canned food.
