CASPER, Wyo. They say animals are at increased danger this time of year.
People have noticed patterns of animals going missing around Halloween time.
Though it is not proven, black cats seem to go missing more often.
"For their own safety if you love your pets keep them indoors. We are still having incidences around town." Said Trish McDaniel of the Humane Society.
McDaniel says it is also smart to keep them inside since there is an influx in both pedestrian and vehicle traffic.
