Klaus is our furry grey kitten mouse. He is Sunny's biological brother, and together, my sister refers to them as the first edition. Klaus particularly enjoys sleeping sideways in the middle of our bed, he has a bit of an ear fetish and tries to lick yours when you are too tired to fight him off and he looooves honeysuckle. He's also a water kitty and will sit with you in the shower. Unlike Sunny, Klaus has filled out his kitten suit very well!
