Now Seattle Aquarium biologist Sara Perry is working with Mishka to get her comfortable with using her inhaler. Like other training maneuvers, Perry uses food to try and entice Mishka to learn to use the inhaler, filled with the same medication used to treat humans with asthma.
...The aquarium said they are unsure why Mishka developed the condition, which is more common in humans, but speculated that it may be due to reduced genetic diversity in the population since they were nearly wiped out in the early 1900's and had to be repopulated with otters from Alaska.
