Not much to say except my kittens love these toys. They dont have the patience for me to put them on the wand. The want the dang feather bell NOW! And they want all of them NOW!The play together with the feather bell and fuzzy worm or alone. The enjoy ripping the feathers out of the toy then play with the bell.I really love that I can buy these replacements in bulk so they always have their favorite toys available.I love how these look when you slowly drag them across the carpet. The cats like to watch it for a little while before they attack and pounce on it.My cat absolutely loves to play with this toy, a little too much. Her hunting instincts seem to kick in strong when playing with these little guys so she usually tears one up in about a week or so if I'm lucky. Ive gone through two bags of these refills now but am just glad they are not too pricy.At first I was worried the small plastic eyes would come off with rough play but somehow they never fall off!I do want to add, please don't leave your cat unattended with this toy if your cat is like mine and can tear off the worm from the pole. I found my cat once with half of the worm down her throat as she was chewing on the rest and had to pull it out. Ever since then, I've never left it out in the open.Overall, a great toy my cat loves, but just be careful that your cat doesn't swallow it(:My cats love this toy, and one of them is actually addicted to it -- he nudges me to play with him with this toy throughout the day, and drags the "worm" (and its attached cord and wand), around until he drops it by my feet. I love the idea that a cord comes with it, to change out the fishing line, although I've never had a problem with the thin wire.I have already bought two of these as gifts for my cat-loving neighbors, and a replacement kit of worms for me. All of my cats love this toy and its dangling feathers, but the worm is undoubtedly a hit.Monty the cat approves. As does my sister, who finds them a necessary accessory for her rearview mirror.It could be my cat chewing on it or something but the rods keep breaking. Otherwise it's an incredible product, my cat absolutely adores it!My cat and I have had many an hour playing with these.
