No Animals Would Be Allowed to Live This Crowded

It has been revealed that there are a lot of business going on in Stockholm regarding false addresses for immigrants. In one flat, 44 square metres big, 50 people were said to live. Some people on the responsible authorities have suspected that this has been going on, but have not reacted. I am a bit surprised. If it would dawn on animal protection agencies that dogs or other animals would live as crowded as this, they would react immediately. Why, then, do not the human authorities who are supposed to take care of humans react, when there are suspicions like this? What will happen to these people? Do they have dogs, and if so, what will happen to their dogs? I wish them well, no matter what.
