After reading a chapter in the Barker's book about cleaning and husbandry and water bowl maintenance, I felt completely "called out" by their "wet thumb" method cleaning being totally ineffective. Basically contaminating and re-contaminating over and over.

And besides, who really wants to sanitize a large number of heavy water bowls week after week every time you change the water.

I finally got motivated and ordered some of those 16 oz deli cups that fit in the water bowl.

A case of 500 cost me $38.99 shipped. Got here in 2 days, although they are pretty close to me, down in VA Beach.

Just wanted to give you guys a heads up to the good source.
