A few days ago, my 10-year-old daughter suffered a sad experience. She had a pair of finches kept in a cage on our back patio. On one occasion, my wife noticed a cat near the cage, attempting to reach its paw through the cage bars. Fortunately, the cat could not fit its paw through the bars to harm the birds. My wife shooed away the cat, and we assumed that, even if the cat returned, it could do no harm.
