　　【Causes and Symptoms】

　　When cats groom themselves, the hair they swallow forms hairballs in the stomach. This condition occurs when the hairball is too large to be vomited up or passed into the intestines. Symptoms include frequent vomiting after meals, with vomitus containing both hairballs and ingested food.

　　【Treatment and Care】

　　If vomiting occurs once every 1 to 2 months and only hairballs are present in the vomitus, there is no need to worry. However, if vomiting becomes too frequent, it is best to have the cat examined at a hospital. While administering medication, owners should also regularly groom their cats to reduce the amount of hair ingested. (Source：PetsZone)
