I've heard animals will eat things because they're lacking something in their diet. Some dogs eat poo for that reason, cats eat grass to help their digestive system. So what is lacking in my cats diet to make her eat a frosted snickerdoodle? I mean, is it possible she's lacking cookies in her diet? Maybe she's lacking frosting? Should I smear a little frosting on her food? The frosting wasn't lard based and she actually ate the cookie as well as the frosting....Stupid cat.
