Yeah you don't, governments do but Turkish authorities aren't really taking such an action. Don't get me wrong, having these stray animals are awful. They are suffering from cold, almost none medical treatment, sickness and sometimes hunger (or bad food). Also some stray dogs attacks kids and whoever seems weak to them. Really the stray dog problem has grown so much but cats aren't a direct problem to humans. People won't let them go since it's better to upload cat pics on instagram so everyone can see how much you love cats meanwhile after you pet it, it will have such a rough night.
