"Rest assured, you do not need the expensive shampoos that vets sell you that are formulated for animals. They are far more expensive and you can bet your bottom dollar that all the human shampoos have already been tested on guinea pigs and proved to be harmless!!" --Peter Gurney

Enough to convince you?
