After a series of diagnostic tests, the veterinary team at the Rescue Centre determined that, in addition to severe health problems caused by stranding, Levi had a large, lung-parasite infection and was suspected to have hearing loss. Over the following months, the veterinary team treated Levi’s lung infection, and worked intensely with him to regain his strength through physiotherapy. Although his progress was slow, he eventually began eating herring on his own and continued to gain strength. By late summer, Levi had begun to display marked improvements. He was swimming on his own, foraging for live fish, and tests showed that his hearing issues had resolved with time.
