We haven’t had a cat cartoon in a few weeks. I have one cat, Scoot, who has crossed the front-door threshold thousands of times. Yet, every time, she approaches it as if it were a ditch of venomous snakes. She assesses it carefully from a respectful distance, as if to gauge how far she will have to spring to clear the snake pit before the vipers see her and can strike. Then, with enthusiastic verbal encouragement from whomever is holding the door, she’ll make her move, clearing the threshold by a good two feet. I think she’s very far-sighted. Or maybe all those catnip-infused treats have fried her brain.
