Look at that silly Prin smiling for the camera. Charles is a stocky built cat and we've noticed that he seems to still be growing. We are estimating his age to be about a year and a half. We think that he shares linage with Norwegian Forest Cats. We recently read that they continue to mature for four years. Wow! He might turn out to be a very big boy. Look at his size already compared to Prin who weighs 60 pounds. They love to play fight. We're hoping to get a video to share. He sure keeps our life lively!
