Thanks everyone! I love the big hug in the last picture too! They have their moments, but overall they really do love each other--they were a good match to get as a set.
Both kitties are "Domestic Medium Hair". I am not quite sure what fur tufts are, but I wouldn't be surprised if that's what he has. Guinny's are actually more prominent, you just can't see them that well in the pictures. They are like clusters of fur between each finger that are longer than the paw itself (is that what a fur tuft is?)
Edit: You can see what I am talking about with Guinny in the picture where she is sitting on the window sill.
