New Zealand scientists have been investing time into a study to determine whether cows can be potty trained, according to scientific journal Modern Biology. What's more is the study has proven to be a success; of 16 cows involved in the project, 11 now use the "MooLoo" whenever the urge strikes them, says lead author Lindsay Matthews. "The cows are at least as good as children, age 2 to 4 years, and at least as quick," Matthews says.
The University of Auckland scientists who conducted the study actually had a good reason to do it: Cow urine contains nitrogen, which becomes ammonia when mixed with feces, Matthews says. And ammonia in the environment leads to acid rain, tainted water supplies and other issues.
