Kittens on the prowl

The four little kittens are now moving freely. They have beautiful blue eyes, their ears are perked up, and they have unanimously become explorers of the wild world they live in. They are rambunctions and love to tumble and play with each other. However, they are much calmer when held by one of us, and they are more timid about where they are. They are all strong, healthy, have a good set of lungs (they can meow up a storm when away from the rest of the litter). The only point of concern is that Mercedes wants to stay away, go outside to hunt, and not be inside with the kittens.
