Grey Squirrels' bite will draw blood.
Chipmunks are very trainable. They will do anything for a sunflower seed. Every Spring, I train chipmunks to come to my whistle! Especially funny to see chipmunks ricocheting across a hundred feet of forest to race to me holding a sunflower seed...Chipmunks have even identified the sound of opening the jar I keep the sunflower seeds in.
In captivity, they live about eight years; in Nature, about five. Most youngsters are chased from the nest while still "naïve" of their predators.
The slowness of our court system guarantees the squirrel won't outlive any verdict.

One minute video of Goetz trying not to get bitten by his playful squirrel. (Also fought eviction in New Hampshire for keeping his squirrel).
