So you’re dozing on the nice fluffy rug when this giant cat comes into your house! As yet it’s only in that flat box that the stupid humans put there. But what if it gets out? Too much for one bulldog to handle–so he calls for backup. “Yo, sis! Get down here right away! We’ve got a giant cat down here!” And, voila–she patters down the steps and joins her brother in warning off the cheetah.
Good thing he slept through the part about the hyenas. They’re much nastier than cheetahs.
