UTC  Summary    First part  I suggest a better introduction to it such as the one I have suggested here today should replace the present one We only have to go back to the birth of modern zootherapy in the  s Boris levinson It could be said that pets have always been around but since Levinsons claims they have never been as popular We can then state all the claims that are being made  Second part  To be fair it should be allowed the same amount of space as the first part it should be clearly stated whats wrong with the first part  the poor quality of the references used to substantiate these claims   the mediocre quality of the studies used to substantiate these claims  the promotion by various interest groups who are often the authors of these claims   each claim should be then criticized  the toll on animals should also be spelled out as they are the innocent victims of this pseudoscience  as a conclusion it should be stated why it is also bad for people  Fair enough     May
