The kitten is settling in nicely. She and the Sherm have become fast friends. I think it's good that he now has an equally energetic playmate. It's also made us realize how sweet he is. He's like a big teddy bear.
Nathan and I can definitely feel a difference having a third cat. Someone is always needing something. I have to keep an eye on the little one like you would a toddler, though I don't think many toddlers can crawl under the couch or behind the washer and dryer. Whenever I lose her I just look for Sherman and he's usually watching her.
