Hmm - I bet if kitty gives him one good nose-scratch (which would be a mess for you, but not so serious as to require vet attention) it'll cure him. Does Scolding him work? Most Saints are sooo sensitive to people that you being angry is the worst thing ever! How about holding the kitty near him, petting the kitty then him, and saying "nice kitty, good kitty, nice doggie, good doggie" in a soothing voice?
