CAT LOVERS buy this toy, My cat had a similar toy that cost me 3 times the price, and she literally ate the butterfly within 5 minutes, my chonky lady attempts to eat anything she can, this toy so far has lasted 4 days butterfly is still attached YAY, however what makes this toy great value for money, is that it comes with an extra butterfly and it also comes with a wee screw driver to open up the battery compartment, I am literally buying a double up as we speak just so I have back up butterfly's :) Hope this review helps my fellow kitty lovers.
