Dallas College professor Patrick Moore, seeing his dog Abbey eating her own poo and swallowing dirty socks, wonders how animal tastebuds work. Danielle Reed, associate director of the Monell Chemical Senses Center, takes a break from feeding her cat Diet Coke to talk about the chemical properties of taste. Both cheese and sweaty socks smell like isovaleric acid. Dogs being omnivores unconstrained by the social cues that govern human behavior are going to go ahead and see if that sock is food. Host Andrew Norton would rather have listeners thinking about Mac and Cheese but he has his own taste issues. Maybe it’s in genetics?
