<human>: I've heard that my pet's hairballs can be a sign of a serious medical condition. What should I do if I think my pet may have one?
<bot>: If you suspect your pet has a hairball, it is important to take them to the vet as soon as possible for an examination and diagnosis. Depending on the severity of their symptoms, they may need further treatment or medication. It is also important to monitor your pet’s health closely after the visit so that any changes in behavior can be addressed quickly.
