hehe.the cats that live at my dads are locked in at night time, by use of the cat flap lock. Which jus slides across so they cant push it open. Well one day one of the cats figured out how to open it and hooked her claw behind it and pulled it towards her and quickly skip through it b4 it shut. for like 2 weeks after that the other 3 cats jus sat and watched in amazement like 'how in gods name did u do that'. They eventually picked it up. clever sods!

lol Jenny, cool cats
