Cats suffering from hairballs may exhibit the following symptoms: frequent dry heaving, sometimes vomiting cylindrical hairballs, hard, dry stools with hair, lethargy, lack of appetite, rough and dull fur, constipation, bloating, and other adverse reactions. 
Hairballs are a common condition in cats. Because cats often lick their fur, the hair they ingest can accumulate in their intestines and become difficult to expel. Once a hairball is in a cat's stomach, it can cause the cat to vomit up the hairball.
The primary task when hairballs appear is to help the cat expel the hairballs smoothly, not to wait for them to pass on their own. Some cats lack fiber and have dry intestines, making it difficult for them to expel hairballs. Forcing them to pass hairballs can damage the intestines and may cause intestinal bleeding. Hairball remedies can be used not only when hairballs appear but also as a preventative measure in daily life.
