Truisms about pets! -------------------------------------------------------------------------------- Some self-evident truths about pets... Buy a dog a toy and it will play with it forever. Buy a cat a present and it will play with the wrapper for 10 minutes.

Dogs and cats instinctively know the exact moment their owners will wake up. Then they wake them 10 minutes sooner. Dog's have owners. Cat's have staff.
