Another seven cats have been found cut in half in the same Maple Ridge neighbourhood where more than a dozen had previously turned up mutilated, according to the BC SPCA.

Spokeswoman Lorie Chortyk said the latest string of disturbing discoveries occurred over the last two weeks in one 13-block area of the Vancouver suburb.

"The pet is placed in a yard or a public park, so it's clear the person doing this wants it to be seen," Chortyk told ctvbc.ca. "Obviously this is a very disturbed individual."

There have been a total of 22 mutilations recorded in the same vicinity since June 2011, but investigators still have no leads about who is responsible.

Each cat has been found severed in the same fashion, Chortyk said, and the SPCA has ruled out the possibility that it is the work of a non-human predator.

"These cats are cut exactly in half using a sharp object, probably a saw or a sharp knife," she said. "To think what these cats have suffered, it's just unfathomable.'

Necropsies have turned up no clues that could help lead to a culprit, nor have several public pleas for help. For now, the SPCA is warning locals to keep a close eye on their pets and, if possible, to keep them indoors.

Anyone with information is asked to call the Maple Ridge branch of the SPCA or the Ridge Meadows RCMP.
