At first, all I could do was laugh.  Once I started thinking about it, I started laughing even more.  I can't figure out which is funnier, that someone believes this is a good idea, or that someone else is going to buy these books and try to adjust his pets.  I've been to the  site.  If this is a joke, it's not readily apparent at first glance.  

So some poor cat out there is in for the experience of at least one of his nine lives.  Personally, I have enough trouble getting a cat to sit still, or at least sit still where I  want him to,  for even the simplest and most pleasant things.  I can't imagine getting one to hold still long enough to get a  chiropractic adjustment.  I wonder if they give you a pair of elbow-length work gloves to protect you from the claws.....

As for the horses, well, that's another and even more frightening story......
