When my cats are home alone, if someone drives up and opens their car door, they get inside. They also leap into moving strollers (with babies inside). Who knows what they'd do if someone came to the door (sigh)
Dog: What is it? Me: It's a tree. Dog: Can I eat it? Dog: *stares blankly* Me: What? Dog: I'm gonna eat it. Me: Once your ass gets a stomach ache I'm gonna let you stay there and grovel in pain because you should have listened.
