(Corvallis, OR) -- A well-known harbor seal at the Oregon Coast Aquarium has been treated at Oregon State University's Veterinary School for a throat problem. 35-year-old Boots is one of the most popular seals at the aquarium, because of the way she interacts with visitors. For several months, she's had trouble swallowing. Veterinarians at OSU gave her a CT scan, and an endoscopic exam that determined she didn't have cancer, but has a ulcer in her throat. They'll treat it by feeding her fish with medicine inside that should help the ulcer heal.
