Frank,

Do you know this Inventor?
She's from Pittsburgh Pa.

I see the date of this patent was 1973, I was wondering if this caught on around there? [Linked Image] [Linked Image]

Bill,

I can't say I remember seeing one. It looks like a good gift for the dog owner that has everything......

It looks like they found it Important enough to Patent in Great Britain and Switzerland too!

I wonder if there was a patent for the Pet Rock?
