AN INCREDIBLY SAD DAY OF TEARS. We put down our 3 year old kitty Marbles this morning. She had a heart murmur from birth and it gradually took over. The vet made the decisiion for us when he said, "It's time. There's nothing we can do." She was the perfect cat and brought great joy to Bob and me every day she pattered up to be part of our family. Marbles spent the last week snuggling on our laps for great stretches, as if she knew the end was coming and wanted to fill it with love and affection. And I held her to the very end.
