You can find the heavy pet water bowls at Dollar Tree, WalMart, Target, etc.
While it's not in their online store so I can't post a link to it, for $3 Target sells a large plastic water/food bowl shaped like this stainless steel one (http://www.walmart.com/ip/Platinum-P...Black/15723401). My husband took his dremel to the side and cut an access hole, so it doubles as a warm-side hide and water bowl for BP's up to about 1000 grams. The base is wider than the top, and none of mine have ever been dumped.
Awesome, thanks! She is like 720ish or something like that, I forget lol. That's a smart idea for a hide/water combined!
