Oliver does not seem to share in my enjoyment of Dan's company. He hisses, spits, gets all puffy, hides, and throws up when Dan comes over. (And Dan really likes Oliver!) Poor guy (well, poor guys!) Oliver actually sat in front of me tonight (in between Dan and I) and howled and growled as Dan was on his way out the door. Anyone have any tips for dealing with a mad, mad kitty?
