Must be Tunnel month,Just a few days ago I was browsing a second hand store and came accross a childs nylon tunnel for $3.Felix adores it.Felix's is red,blue&yellow its 3 1/2 feet long and the opening is 1 1/2 feet wide.He reacted the same way as your kittys did when I came home with it Woohoo I am going to see if we get one of those free with food here where I live
