This may seem like it's splitting hairs but I assure it is not, it's CORRECTLY setting the stage of comprehension, as what comes next will give this clarity. 

Just in my circles I know a lot of restaurant owners,  contractors, bar tenders and hair dressers that I am sure are near the poverty line on their tax returns but are no where close to it in real life.

Happy New Year LynnOK ,,,the matter of shower drains,,,The most common cause of a shower drain stoppage in my experience has been long hair in the drain as a result of our dear womenfolk shampooing in the shower.In all fairness a guys hair will clog it up too,,,especially if he's a wanna be Rock Star ,,,hair is hair.!!!!

For some houses that are pet free they have new ductwork, never exposed to pet hair, etc.
