LOL, this is good laugh. Gramps got the kittens good.

...Oh, Boxcat is in the house in the Lady’s master closet. He was there before Grumpy Grampa and his kittens were adopted in by the Lady. Grumpy Grampa has only seen Boxcat a few times in his life, whereas the kittens have only heard of him from Grumpy Grampa’s ‘stories’. Maybe he was exaggerating Boxcat’s existence... or maybe he wasn’t? But it is known as a silent rule that no cat in the house, especially Boxcat should never or has ever actually hurt the Lady of the house. You’ll just have to keep an eye out for another strip! I’m glad you enjoyed it :3
