Dexter told Delilah that bathing is a very important to a cat. In fact, after eating and sleeping, it is the most important thing in life. He was giving her bathing lessons the other day and Delilah was a very quick learner. In fact, she even practiced on Dexter too.
By the end of the lesson, Dexter told Delilah that she was doing a very good job, but she needs to remember to to clean behind her ears, and the tip of her tail. It is also critical to keep her whiskers free from cobwebs. He noticed recently that after their hunting expeditions in the basement, she had cobwebs on her whiskers all day long.
