The Ontario Society for the Prevention of Cruelty to Animals said yesterday that it has suspended the Toronto Humane Society as a member after investigators searched one of its shelters and found four cats in “serious” condition.

A statement from the OSPCA said investigators discovered animals in distress and immediate intervention was required due to “potential loss of life.”

But the Toronto Humane Society said it felt vindicated by the “surprise inspection,” given that the vast majority of the 1,100 animals examined were fine and none were found to be suffering or in need of being euthanized.

Investigators were at the shelter Tuesday as part of a probe into allegations of inappropriate conduct at the shelter, which was prompted by a series of newspaper articles in which some people alleged animals were suffering because of a restrictive euthanasia policy.
