Owlaholics Unanymous 

Owlaholics Unanymous is a burrowship of men and women, (on Facebook in the group Owliacs), who share their experience, strength and hope with each other that they may perpatuate their common obcession and help others to discover owlaholism.
The only requirement for membership is a desire to begin or continue to perpetuate OWLAHOLISM, (as defined in the Urban Dictionary). There are no dues or fees for O.U. membership; we are self- sustaining through our own mental illness with owls.

O.U. is not allied with any sect, denomination, politics, or institution; and wishes to engage in any and all owl controversies, as well as totally endorsing or opposing anything or anyone having to do with our worship and veneration of the owl. Our primary purpose is to stay Owlaholics and help others to achieve full blown Owlaholism.

After years of pain and loneliness as a result of constant thoughts of owls, Ivonne finally felt "a part of", after going to her first Owlaholics Unanymous meeting.
