When we first got Dudley a few years ago, he was terrified of the toilet - he wouldn't even come into the bathroom! As time went by he finally got the courage to come into the room, but nowhere near the toilet - then he finally approached the toilet in that "slinky" position, with his tummy low and his tail tucked, but if we flushed it, he'd run. He is finally at the stage where he can stand up and peek over the side, and if the lid is down he uses it as a springboard to get up in the window, but he still runs off whenever we flush - he's such a Nervous Nelly!
