It is actually a normal physiological manifestation for cats to hiccup after eating. If the hiccup symptoms disappear within a day, the owner does not need to worry too much. Common causes of frequent hiccups in cats include eating cat food too quickly or too much. It is recommended that owners pay attention to the amount of cat food when feeding their cats daily, and try to let them eat less and more frequently. You can also prepare some probiotics every day to regulate their gastrointestinal tract.
