all animals will turn carnivorous if it suits their dietary needs.
don't believe me? try cutting the head off a chicken and watch the others rush in to get at the head.
a while back there was a similar stink because deer were found eating gut piles. it was assumed that they were simply after the stomachs as they are often filled with prechewed and semi digested plant material which is excellent for animals getting ready to enter winter hardships. then again hearts are rich in protein, spleens rich in Iron, and liver is rich in potassium, phosphorous, and vitamins A,D,E, and C, more than what is available in any naturally occuring plants so I could easily see an animal that knows it's about to stop dining well(autumn) or has just completed a long period of substandard diet(early spring) coming across a gut pile or a nest full of eggs or chicks and chowing down to fill dietary requirements.
