DO CATS SEE GHOSTS? (my cat does) (^..^)

Here is our cat, Prince, having one of his "attacks." He often has these. We think he sees either invisable ghosts or monsters. We only hope we never see what he sees! LOL UPDATE: Sadly, Prince passed away on April 2, 2011. We will always remember him. PLEASE SEE OUR MEMORIAL VIDEO THAT WE TOOK THE DAY WE SAID GOOD BYE TO HIM. (^..^)
