DM's Note: No one saw what the others were seeing. Which is really too bad, because that cat was pretty rad.
Tip: Group hallucinations can be a great way to avoid total party kills.
DM Tip: If you haven't tried it yet, give your players an earthquake. Be sure to give frequent reflex saves WHILE they are bickering about what to do. I guarantee you'll get a kick out of it. Don't forget flying objects and rampaging horses.
