Interesting. That coyote ought to be dead or dying from gossy pol poisoning. All of them need to eat cotton seed and die. May be vomit and not scat??
Definitely scat. While the pic doesn't show it, the pile had perfect "fecal formation" if you know what I mean. Actually, I think I saw another pile a few hundred yards away that looked the same. Full of cottonseed. Your gossypol comment got me to thinking and I searched and found this from Wiki:
Toxicity and potential food source
Food and animal agricultural industries must manage cotton-derivative product levels to avoid toxicity. For example, only ruminant microflora can digest gossypol, but only to a certain level, and cottonseed oil must be refined.
A research team at Texas A&M University has genetically engineered cotton plants that contain very little gossypol in the seed, but still contain the compound in the stems and leaves. This provides protection against pests and diseases, while allowing the seed to be used for oil and meal for human consumption. The plants are modified by RNA interference, shutting down the genes for gossypol production in the seed, while leaving them unaffected in the rest of the plant. The resulting gossypol-free cottonseed is then suitable as a high-quality protein source suitable for consumption not only by cattle, but also by humans. Protein makes up 23% of the cottonseed.
Maybe this is why the yotes are able to eat and survive?
