In Marin County, California, Corey Nolan Reed (of 809 Wilson Ave, Novato, CA), was arrested on suspicion of attempted cat poisoning after reports that he’d been observed pouring a green liquid–believed to be antifreeze–in bowls left out for the feral cats who live at the North Marin Water District’s Novato facility.

“Based on eyewitness accounts and people who consistently monitor the area, this person was always a person of interest,” Marin Humane Society spokesperson Carrie Harrington said.

Fortunately, it appears that no cats were sickened or killed in the attempt, according to Harrington.

About 25 feral cats live near the Rush Creek Place facility, and community volunteers leave bowls of food out for them, Harrington said. Marinwood resident Janet Williams, co-founder and president of Marin Friends of Ferals, a nonprofit organization that helps look after the animals, said she wasn’t surprised by the incident.

“There are people out there that really don’t like ferals,” she said. “I also knew (volunteer feeders) were having problems with water district employees.”

Williams said that some employees do help look after the feral cat population, but others have threatened or harassed the people feeding the cats.

Although the district is not responsible for the feral colony’s care, it helps the volunteers who tend the colony by occasionally paying for spays and neuters or by feeding the cats.
