Caesar is 11 1/2 years old and spends most of his time sleeping or thinking of food. Tessa is 2 months old and spends most of her time sleeping or peeing in inappropriate places (even after I've just taken her out for a potty break). Up until now, Caesar has spent most of their time together loftily ignoring her, or trying to get as far away as possible. But starting about 15 minutes ago, he's now sharing his favorite blanket with her and licking her and chasing her around and they're both as happy as can be. So good to see!
