CuBowls are the only unlacquered, thickly copper and silver plated pet bowls. Cubowls are beautiful, but more than that they are uniquely functional. Pets and people love that they are cleaner due to the oligodynamic effect. Bacteria, Viruses, and fungi are effectively destroyed. Your pets water source will go from disgusting and slimy to incredibly crystal clear. Most pets are fascinated, drink heartily, and ignore their old bowls.
