Los Angeles County Animal Care and Control said in an Instagram post that it received a handwritten letter in the mail from a local girl named Madeline.

The post said officials received "so much joy" from the letter that they decided to respond. "We commend Madeline's sense of responsible pet ownership to seek permission in advance to keep a unicorn in Los Angeles County. As a result, we issued her a pre-approved unicorn license," the post said.

The conditions listed in the department's response to Madeline for the license included requiring that "the unicorn is given regular access to sunlight, moonbeams and rainbows."
