Pet Scent Training
A set of scents, in spray bottles, specified for a particular pet type and function.
Each scent represents an activity you would like your pet to do. Using their sense of smell they know to go outside, eat, sleep, use an indoor bathroom, stop making noise, or some other cognitive behavioral task. The scent is designed to disappear after a certain amount of time.
Reward: To train a rat in a maze by smell.
