<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. A veterinarian will be able to assess the situation and provide any necessary treatment. Depending on the severity of the issue, your pet may need surgery or other medical attention. It is also important to keep your pet clean and groomed regularly so they are less likely to produce hairballs in the first place.
