I've been to two different Petsmarts in my area and they are clearing out 7.5 inch crock water bowls out of their reptile section. Normally they are $12.99, but they are on clearance for $6.99. These are large enough for your big girls to bowl wrap, heavy enough to be non-tippable, will last a lifetime, and lack the decorations found on dog and cat bowls. If you're in the San Diego area, I've already cleared out the Chula Vista and Sports Arena Petsmarts. Go get em!
