Susan M. Miller, 43, of Naperville, Ill., was charged with disorderly conduct, the Chicago Tribune.
Naperville police say Miller also took a sign advising apartment residents to clean up after their dogs and placed it, along with green plastic bags used for cleaning up dog waste, on the same neighbor's patio.
When police arrived at the apartment in answer to a complaint, they found Miller chasing a cat through the complex.
She yelled at the officers, asking if they "were there about the (neighbor) with dog poop," the police report said.
Police arrested Miller -- after she caught up with her roommate's cat, the report said.
Miller was later released on bail.
