I also have a cat and a Yorkie. My 11 year old tuxedo cat Avery tolerates Sophie Kate just fine. Sophie Kate love, love, loves the cat and will kiss him and attempt to cuddle with him.
Last weekend Sophie Kate went for her 1 year booster shots and did not do so well, she was groggy and really sore and wanted nothing to do with me. The only comfort she found was cuddled up next to Avery on the bed, it was so sweet Avery guarded Sophie Kate all day while she napped.
The only thing I would suggest is teach the dog boundaries. Sophie Kate is not allowed to be bossy or jealous of Avery (he is my first love0 but she will if not reminded daily.
