MONROE - More than two dozen Monroe pet owners are concerned that their missing cats may have been held in captivity by a Monroe cat hoarder. The Green County Humane Society has received almost 15 separate inquiries from worried cat owners since Delores Marti of Monroe was discovered to be in possession of 50 live cats and nearly as many dead ones last week. Marti was found to be keeping the cats in a house on 19th Street in squalid conditions.
