"This is a very isolated incident," Ted Munro, an inspector with the Royal Canadian Mounted Police, told the National Post.
"I just think it's some idiot that made a bad decision, a really bad decision," festival marketing director Kim Blevins told the National Post. "And hopefully he'll pay for it."
In the meantime, concert organizers say they plan on helping Jamboree find a home.
"In all of our years in entertainment and working festivals and fairs, we have never experienced an incident like this," musician Bruce Williams said in a video posted to the event's Facebook page, adding the kitten "will become the official mascot of the Jamboree."
