Yes, these will also end up under your sofa...
I'm not sure if boinks are most fun for cats or humans, I know I have a blast when playing with them together with my cats.
You will have a pack of 6 boinks like the photo shows.
Why are they black and white?
Read my Theory of Black and White to get the full info about this. It has to do with how cats sees things and it might be the perfect change for you if you have a "4 AM:er"? Your cat needs toys that is more visible to him/her during the night and these are exactly that!
Take a look at the extra photos and see the difference in visibility because the colored toys lack contrasts.
