I think pet-proofing a home is just as difficult as child-proofing it. It even has a few added twists. After all, a baby can't leap to the highest curtain rod and hang from the drapes. And they don't usually pee in the potted plants. No, scratch that second one; it has been done.
As with babies, all noxious substances have to be secured from the paws of cats. After all babies who spit out pureed peaches as unpalatable, and cats who refuse to eat any food not featured on the TV commercial with the white cat on the cushion, have the same reaction to a bottle of Lysol. Hmm, now that might taste interesting.
It boils down to the fact that babies and cats are the two most inquisitive creatures on the planet. It may be a pain trying to keep them out of trouble, but we wouldn't have them any other way, would we?
