Many cat owners see a hairball and think:

Hairballs are often a symptom—not the root problem.

Veterinary medicine has shifted how we view “hairball cats.”

We now recognize that many cats with frequent hairballs may actually have:

Chronic hairballs deserve a broader medical look—not just repeated remedies.

Over the years, I’ve heard many owners say:
“She’s always been a hairball cat.”
