Nikki is 235-pound Siberian tiger that was having her physical last week.
When Nikki went under the gas the Oregon Zoo brought in a dozen children who were all visually-impaired, and a few who were completely blind.
Ten-year-old Zoe Christian-Parker said Nikki's paws smelled like sweaty feet.
Programs like this allow visually-impaired children to learn more about animals.
But it also lets the children socialize with other children with similar disabilities.
And Nikki gets a nice check-up out of it.
