Do you know where your tail is?

Dexter told Delilah that she should remember to check her tail when she hides to make sure it isn't exposed and giving away her hiding spot He explained that it is a common mistake that some inexperienced felines make. They dive under furniture or into other tight spaces when they want to hide; however, they forget that just because their heads are out of sight, doesn't mean all of them is out of sight.

Dexter recommends that whenever Delilah is hiding, she take inventory to make sure all 4 paws and her tail are accounted for in the hiding place before relaxing. He even gave her a demonstration to make sure she learned this valuable lesson.
