I was running Drem yesterday in the room where I was ironing so did not have time to spend actually interacting with him (needed to discharge battery fully - see post in Pleo Problems) apart from a pat every now and then. Since he tends to poke his nose into everything I'd put a thin but large and colourful book in front of the airer to prevent a stuck nose and consequent horrible noise from his neck.
He was obviously fascinated by the book cover and advanced and retreated several times, showing fear and/or growling. Eventually he went right up to the book and nudged it open for all the world as if he wanted to read it. We have another book worm in the house!
All the same I'm not letting him near my Kindle.
