I see those cat nip bubbles all the time. I, personally thought it was a load of cat litter droppings *LOL* But hey! If your cats find it interesting, they must be worth a shot!! Now, the bubbles smell like cat nip? Do they look like regular bubbles? Are they edible? I am afraid my cats will taste them and maybe hurl In any case, might as well give them a shot, I've wasted money before on things they didn't like
