Bo gets her spurts of energy in the evening, after mealtime or after receiving a good snack. She'll tear through the house as if being chased, then with two leaps reach the top shelf of her 6 foot high penthouse. Then she jumps down, repeats the process and after a few of these antics decides to lay down and go to sleep. She is still quite playful at 14 years old, she will beg for attention by running to her toys and laying down on top of them, then looking at me with those liquid gold eyes! I usually can't resist.
