A Ghost Story ?

Woke up last night a little after midnight, thought I heard someone urinating in my master bath. Set up slowly looked around, it was quite dark. I saw nothing and could only hear the strong westerly wind that blew all night. I invetigated throughout the house. Saw nothing out of place but noticed we had neglected to lock the back door. Stepped out the dogs were all sleeping and came to me as I scanned the yard. Humm I fed the dogs locked the door and returned to bed. At 0600 I again awoke to the strange tinkling sound, this time my wife heard it as well she said "what the hell"? Taking my combat light and .45 off of the night stand I shinned the light into the bathroom. There on the toilet sat my CAT! The look on her face said it all "WHAT never seen a cat piss in a toilet before" ? My wife and I were almost late for work and gettin my boys to school , couldnt stop laughing. Anyone know how to teach a cat to flush?
