Well, one thing can be said for certain: The cords which the lights are attached to are very smooth and slippery and can't be used as a bridge to the next branch of the tree.

As one little shapeshifter cat just found out.

There's a clattering jingling sound as lights hit each other and a crashing of branches above Sync, and then a black kitten comes crashing down from further up the tree, threatening to drop down exactly on Sync's head if he doesn't move out of the way quickly enough. At least she has turned around already so that she would hit him legs and claws first?
