Rascal, about six years old, is my sister's cat. To put it bluntly, he is an goosedown. Today the puppy got to meet him and he just hisses and howls. I'm unsure if he'd go as far as biting. Rascal even hissed at me when I reached my hand out to him. Needless to say, Rascal is going to be thinking about what he's done in my sister's room for a while.
