I could've purchased regular bubbles for the same effect. My cats rather watch the bubbles hit the ground than go after them. Every cat is different I guess, however I think this being "catnip scented" or whatever the case is, is just a gimmick. The liquid is a greenish-blue and did leave a spot or two on my carpet, completely my fault for not being more cautious. Just a heads up to anyone that might purchase. I probably wouldn't buy again.
