I bought some heavy non-tip non-skid plastic bowls with a stainless liner, then I got a tool drawer non-skid liner to put underneath the bowls to make it so they move even less, and the whole contraption sits in a boot mat so that if he does spill some water it is somewhat contained by the lip of the mat.
