Xena, Warrior Princess

Xena, the first Maine Coon I have ever had, is one of the sweetest cats.  

Unusual characteristics of the breed include:  

A Maine Coon Cat has large, well tufted paws to allow ability to walk on top of snow despite size and weight. Ears are large and well tufted for protection and warmth. 

Maine Coon Cats are intelligent, trainable, described as “dog like.”

The Maine Coon Cat has a silky and somewhat oily coat, it is not dense and its upkeep is much easier than that of other longhaired breeds. The coat is almost self-maintained but will require occasional grooming.

Luckily for these difficult letters on the A to Z posts, I have animals named for both X and Z (call it calculated).
