Dongle Keeper for Blinds

My cat keeps playing with/ eating the stings from the blinds when they are open. I've tried tucking them in but they keep falling down.

Short of buying a clip to mount next to each window this may be a good solution.

It slides on to any of the horizontal blinds and has two funnel type slots. Each wide enough to fit the string through and seat each dongle.

Will print tonight, unless someone beats me to it.
