<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 are concerned about your pet having a hairball, it is important to take them to the vet as soon as possible for an examination. A veterinarian will be able to assess whether or not your pet has a hairball and determine what needs to be done to address it. Depending on the severity of the issue, treatment may include medications, dietary changes, or even surgery. It is best to consult with your vet to determine the best course of action.
