Cassi is almost 10 months old and loves to play all the time. As soon as I look at her, she'll run and grab one of her toys to play fetch. If I just ignore her, she'll do this running jump where she plants all four paws on my leg and rebound from it. Ocassionally, she'll settle down and gnaw on her rope, but it never last that long before she's up and about doing something else.
