Horrible product and do not recommend.  Knew it was going to be bad when I almost couldn't get the seal off.  The wand drips constantly so you end up with green stains on your floors (because of the artificial green color).  And the bubbles are not only difficult to get but must not be much of a catnip smell because my 4 cats hate them.  I was also very unhappy to see they are made in China - with the track record of products from that country I will not be using these with my pets anymore.
