A delicacy made out of a can of tuna and powdered glass. Mix the glass into the tuna, and serve to cats. The cats will love it as it cuts through their teeth and gums, and will enjoy the experience of crapping it out, if they live long enough.
"Honey, those stray cats are coming around again. I think we better give them Tuna a la Glass this time."
