A viral video show's a goat named Timur and a Siberian tiger playfully running around the tiger's pen together at Primorye Safari Park in Russia.
The zoo, which is home to several rehabilitated tigers, brought Timur in to serve as live prey for the tiger but the two wound up hitting it off instead.
Their relationship goes beyond simply being playmates, as the park's staff claims Timur has a calming effect on the tiger.
"Amur the tiger used to roar frequently -- both during the day and at night," a blog post on the zoo's website read. "Following the firendship with Timur, the roaring has practically stopped, the tiger has become calmer."
Timur's impact on Amur's roaring was no coincidence as the tiger began roaring again after being separated from the goat for a night.
"They are as inseparable and peaceful as ever," park director Dmitry Mezentsev said.
