Meanwhile, ... Back at the Lab, The Toilet Duck works on.........

An agricultural company worried at the amount of nitrogen leaching from pasture has invented a spray device to attach to the tails of dairy cattle.
The Tail-Activated Urine-Incorporation of Nitrogen Extender system will fire a blast of nitrogen inhibitor into the urine patch every time the beast lifts its tail to answer the call of nature.
A switch will be mounted under the tail to trigger spraycans attached to the animal's ankle.
Well they could put in a deoderant and a fly spray too......
