I have 2 high energy 10 month old kittens. The minute I turned this on, they were hooked. Kept them busy while I cleaned and cooked. When I was finished, they were so exhausted they went straight to sleep and slept the all night.I'm not sure how "stretch" and/or "thickness" apply to this kitty toy, but it's certainly very cute, durable and has a cool laser. My kitties, however, are both hard to please & get bored faster than most, (I've had many kitties), these two bore easily. Both kitties play with this laser for about 5 min then lay down to watch it. IMO kitties would be more entertained if the laser had different modes & patterns bc once they figure it out, they become bored.Keeps my cats busyNot bad, but the laser doesn’t point down… so it kinda just shines on the walls. The laser moves too fast to be enjoyable as well. I wouldn’t buy it if I knew this before.Great quality love how it spends all the way around and my cats love it. I take one star away only because it could be just alittle slower.When it got to us we put the batteries in and got our cats to come see what we had and it just did not even qork... it was kind of comical besides the money we lost placing the ordera bit noisy but tolerable for myself. the motor will not last long even with battery changes faster than i can put them in. meaning a couple of days.
