Strange parenting

Have you ever wondered about those people who treat their pets as if they are substitute children?  I saw a television special once about a lady who had a pet monkey who wore diapers and who she would take to the park to play by walking him there in a stroller.  It made me wonder...if her "baby" gets sick, who would she take him to?  A doctor or an animal clinic?  The animal clinic seems a much more appropriate place to me, but with the obvious emotional attachment factor, would she attempt a doctor?  If she were so bold, would the doctor refer her to an animal clinic?  How much expertise does an MD have when it comes to a monkey?  I can't remember where she was, someplace sunny like Dallas.  Wherever she is though, I would not want to be the animal clinic specialist who has to watch the monkey while she goes on vacation.  Wait...I made a gross assumption.  There is potential for a nanny or babysitter, but seriously, how would you explain that this very well treated monkey would need to sleep in a kennel like enclosure?  I think pandemonium would ensue.  That is what any good parent would do...right?
