The internet is full of information about cranial plates, cranial bones, cranial therapy, craniopathy, etc. It was first promoted in the 1920's and has taken on new names and forms ever since. C.A.T.S. is just a chiropractor specific technique and name for an old idea.

The claims for C.A.T.S. are quite amazing. They claim it can help anything from insomnia and PCS to Down's Syndrome, ADD, ADHD, OCD, Dyslexia, learning disabilities, etc.

Personally, I would not spend the grocery money on it.
