Worse, his only cool water lies in a "tiny pool" that's 20 inches deep, the Mirror reports.
A Change.org petition to have him moved to a Canadian zoo has generated nearly 30,000 signatures as of this writing, but an earlier discussion about moving him there fizzled when Mendoza Zoo lacked three years of health records on Arturo, which is required by Canadian law, the Winnipeg Sun reports.
