Residents in the southeast community of Deer Run are concerned, after posters were left on mailboxes appearing to threaten neighbourhood cats.

Images of the animals were included, along with the message: “if these are your cats, keep them off my property or they won’t be coming home.”

This isn’t the first time the signs have popped up.

Karen Meggert told CityNews, she doesn’t want to throw around blame.

“But I don’t want my animals, or even the kids around here to worry that there’s a threat, or somebody threatening our animals out here. These animals are owned by people. They’re not strays. Little kids own these animals,” she said.

Doug Anderson, with Calgary Community Standards, said cat owners should be responsible, and keep their pets on their property, as they could actually be fined.

“There’s also a risk, when a cat’s running loose, obviously, with traffic or with situations like we see here,” he said.

At the same time, he says the message is concerning, and encourages anyone having problems with their neighbours to contact the proper channels, rather than resorting to vague threats.

Anderson said if Calgarians are concerned harm may come to their animals, they should notify the Humane Society.

If it is serious enough, the police could become involved.
