I agree that maybe Winston is bored and needs his mind occupying whilst you're gone. We were lucky with Sally as she never chewed anything but Lois got into all kinds when she was a few months old. Lois chewed the skirting board and doors and picked the bottoms off my vertical blinds! Potatoes would be all over the floor and she loved the oven gloves! We then bought a crate and she loves it. The crate is the best thing we bought even though I didn't like the idea at first. Now I know Lois is safe and my house is safe while we're gone. As for the kongs my two love them but they dont last long even when frozen they get through them in 5 mins.
