Shoot me for saying this but cat doesn't serve a purpose other than companionship. Dogs on the other hand are protective, loyal, submissive. These might play a subconscious role with cat/dog people. Cat also means laziness and no walking them outside, running with them, hiking, parks etc. Also the article didn't mention if these people had cats or dogs in the past. Dog owners or anyone who participated interacted with dogs will have a bias towards cat owners.
