My sister and her family recently moved across the country, just a few days after their pet cat gave birth to four kittens. When my sister’s family arrived in their new state of residence, they stayed with a friend of a friend while they looked for a new home. These hospitable strangers owned a dog. A couple days into their stay as house guests, my sister and her husband heard their three-year-old daughter screaming. They ran to her aid but they were too late. The dog had killed all four kittens and my tiny little niece had witnessed the tragedy.
