The older cat, Malcolm, kept coming near him but running off if he tried to come at it/play. But he's intensely interested and seems more cautious than scared. The slightly younger one, Fezzik, pretty much stayed upstairs the whole time yesterday and seems pretty freaked. When he smelled my hand after I'd been holding the dog, he hissed. But he's stopped doing that.
Fezzik was pretty scared of my roommate's dog at first, too, but after awhile he was laying down next to him sometimes. So I think this'll pass, especially since he's bigger than him.
