The Voyeur is an adult male cat, neutered, and the alpha of his pack. he's established that Sam is not a threat, but that the dog still outranks him.
I can handle the late night concerts and the tendency to be underfoot, but he deliberately pees in inappropriate locations, particularly when I am watching. Shoes I can wash and carpets can be cleaned, but he's attacking library books.
(Is it felicide to murder a cat?)
