My younger cat, who I've had for 2.5 years, has for the past two Christmases chewed the lights - he's destroyed three sets as well as putting himself at a lot of risk - God knows how he hasn't had a shock. Has anyone got a solution for this apart from not having any lights on the tree at all? Last year I wrapped thick insulating tape all around the cable, but he just climbed into the tree and bit through one of the wires between the lights. Battery operated lights would be safer, but he'd probably still wreck them. Just wondering if anyone had used one of those cat tunnels that you wrap round the tree like a skirt, though I have to wonder at the logic of actually attracting the cat to play around the bottom of the tree
