gsea, we have been thinking of every thing from a toxic range plant to disease or a cat. After a detailed skinning effort. I only found 2 small marks in his right flank, the size of a finish nail and 1" apart. NO other marks on his entire body which had a blood clot around it. When I opened his cavity it was full of blood. Which I poured out. It just ran out. So, my dog found him decently fresh. His liver, spleen, heart and lungs all looked of good color and normal. His stomach had the normal substances of range grass in it. Nothing that I would be concerned about. He had about a dozen ticks on him. Still, normal for this time of year. So, I suspect a large rattler struck him and during his struggle
to free himself. (twisting and jumping) A fang could have cut or punctured the artery that runs the length of the spine (one hole was near this area). Thus, causing the cavity to fill. Which was a lucky happening for this Blacktailed Jack rabbit. This caused him to bleed out quickly
and not have to suffer a lingering death brought on from the venom of the rattler. This rabbit being # 16 that we have found in this condition is alarming to us.
And points to the possibility that we have a rattler problem. They are good hunters and killers then the prey is too large for them to eat.
No telling what other animals they will strike. We have expensive registered livestock here and humans. So, we are more so now on the look
out for this danger. DM
