Cats loved them but didn't last 24 hours
As soon as the delivery arrived (and after the cats had inspected the box) we gave the pillows to ours cats. They went crazy playing with them, we've never seen them react like that to a new toy.
Unfortunately they managed to rip open one of the pillows in less than 24 hours (by ripping the material, not the stitching). The other one is still intact but I'm not sure how much longer it'll last. Good idea, but poor quality material.
