Santino, another clever chimp, who's at www.livesofanimals.org/2009/03/santino-rocks/

This shows us more fascinating evidence about the sentience of chimps. In this case, Sakura is in a human-designed, captive environment, which may be somewhat enriched, but which is still unnatural for a chimp. The fact that Sakura works out what to do in these circumstances tells us even more about chimp awareness and understanding. These abilities are strong indicators of animal sentience.

Sakura is not alone in preferring sweet music. Back in 2001, there was research investigating how cows reacted to fast beats or to softer music. The researchers said: “We found that slow music improved milk yields perhaps because it relaxes the cows in much the same way as it relaxes humans.”

Despite increasing awareness of animal sentience, there is still resistance to appreciating or acknowledging that animals are sentient beings and there is reluctance to peer over the barrier of “human vs other animals” that we ourselves have created.

It was previously thought that this kind of choice and preference about music was a “uniquely human trait.” So we see that Sakura and the dairy cows have overcome yet another barrier!
