I just rescued a kitten from a shelter about 3 months ago to be a companion for my 1 1/2 old 3lb yorkie. They LOVE each other. They are constantly playing. After a while the cat does get annoyed with Cole but will just go somewhere he can't get to. The cat is already twice the size of my yorkie so I am glad I got him as a kitten when they were about the same size. Oh and I must have lucked out because my yorkie DOES NOT eat the cat poo!!
