Ok, not really....its just a joke, but its a joke that might not be that far off.
First of all, its a product called Pet Sweep and its four small mop-like slippers that fit on the feet of your dog or cat and then they dust the floors ( and clean them) as they walk around your home....or if the cats are like mine, as they sit and walk on the table tops, the counters, basically they places I don't want them!
Reality check - No. No dog or cat that I know of would actually keep the things on their feet, allowing that you were even able to get them on in the first place. BUT...just think of it for a moment!!!
My Mom bought me a pair of human slippers that have a mop-like bottom on them...they really do make them...altho No, I haven't used them! But that means that it really IS an idea that could be possible. AND people are always dressing up their cats and dogs...sweaters, coats, halloween....and I have even seen on some web sites that they offer wigs and such for cats too! ( Something only those with tin foil hats likely order tho.... )
So it COULD happen. And really, for all you do for the animals in your family...food, care, love....its only reasonable that they find a way to give back...by finally helping to clean the house!!!
Or at least dust the places that I never seem to remember to get!
