No but its fascinating.. wonder if the cats will use it. Seems to me that those pee drops on the little test pad hes got are awfully small.. so what happens when a diabetic/CRD kitty lets loose the floodgates? Will there be a layer of pee over the top? Will cats use it after its been used once? Cuz then they have to get wet with urine!?
Seems like one of those ideas thats great on paper that might not work in real life with real cats
