Our wiggly wagglers came yesterday too Lisa.
I waited ages for the cats to go upstairs and sneaked them out for a quick look. Within seconds Tommy, one of our kittens was on the end of it going crazy, hanging on to it and attacking me when I tried to take it away. The only way I could get him off was to bribe him with treats. I will now wrap them for christmas but it is definitely looking like they will like them.
