<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>: It is important to take your pet to the veterinarian as soon as possible if you suspect they may have a hairball. The vet will examine your pet and determine if there are any underlying health problems that could cause them to form more frequent or larger hairballs. If so, the vet can recommend treatments to help reduce the frequency of hairballs.
