The Michigan Humane Society has a summer ad campaign designed to help adult cats find homes. Touting them as "certified pre-owned cats," the shelter has a no-cost adoption program and offers a free "multipoint inspection," including spay or neuter surgery, vaccinations, behavioral evaluation, and grooming. With summers bringing an influx of cats to shelters, this campaign is hoping to help alleviate the strain. The Michigan Humane Society has been pleased with the success of the campaign so far.
