cups

4 bowls of oatmeal use 4 fluid ounces x 4 = <<4*4=16>>16 fluid ounces of water.

The amount of water left in the pot is 32 fluid ounces - 16 fluid ounces = <<32-16=16>>16 fluid ounces.
There are 16 fluid ounces / 8 fluid ounces in 1 cup = <<16/8=2>>2 cups of water left in the pot. Answer: \boxed{2}.
