Most of us enjoy a good challenge. Pet dogs and cats are naturally good hunters. By providing our pets with activities that challenge them to use their senses to hunt for food, we can increase their mental well being. Using their abilities to track a scent and manipulate an object to extract food are behaviors that we might observe in the wild relatives of our pets. Practicing species-typical behavior is an important part or preventing behavior problems. There are many ways to provide mental stimulation, but an easy one during Springtime involves using plastic eggs.
