Thank you Whiteboy. 

Heres some pictures..

So the neck is broken? Looks like a bite mark on the neck in the 2nd photo? Or am I seeing things... 

Looks like something was holding her down by her neck, there is marks all over it but no broken or torn skin, I moved her neck around and you could hear crunching or grinding like broken bone, so pretty sure it was broken.. I have 3 older goats that stay out 24/7 for the last 3 years and nothing has ever bother them. One of them is so old and crippled and cant run, so I dont get why whatever it was wanted to get in the pen and make a kill. 

I'm not by any means,  an expert on wildlife, but I'm going to say this doesn't look like coyotes to me. I've seen plenty of calves and deer ripped up by coyotes and this just doesnt fit the typical coyote MO. but that doesn't mean it couldn't be either though.. maybe a larger pack moving thru. Broken neck screams cat to me. I could be totally wrong, it's been known to happen

The thing about cats is they don't often eat a bunch right away. We live an hour from the southern Black Hills and the hills are crawling with cats. We occasionally get one through and neighbors have lost colts, calves and sheep to them. They generally drag the carcass off and bury it under brush and leaves. They let it stew and soften and come back at night to eat.

Coyotes seem to hamstring most of the sheep they kill around here, but I suppose with a pair, one might go for the throat. Could it be dogs, they can sure nab by the neck, but most dogs kill for pleasure vs food?

I have had dogs kill for the fun of it years ago and they always went for the backend, they never went for the throat, and they would maul more then one, the last attack they mauled at least 6 adult does 2 died and had to shoot 3 and my one doe made it, but shes got a stiff back leg now and has the run of the place sense shes crippled now and a blind one runs with her and a adult child stays with the old doe, the one that was killed was in a pen with about 11 more. Thats why I'm so puzzled about only one getting kill and the others were not touched. But I did send another BB a few pictures and they said it was coyote's so I have my fingers cross that it was a coyote. Talked to a Game Warden today and she was telling my husband that a mountain lion was spotted a couple of roads over, no more then a mile from us not to long ago. So we have a game camera set up, the pood girls did not go back into their pen this evening so they are now hanging out in front of my hay barn, I left all the lights on so hopefully that will help if what ever it was does come back and wont go into the lights.

I'm no expert either, but this is just so different from what I have seen in the past. I just hope that it was coyotes or coyote. What ever did this it happen super early this morning. 

That seems to always be when coyotes attack ... early am. We lost several chickens when we accidentally left the coop open the hens decided to venture out right at dawn and I saw a coyote running off with one. Hate those buggers so much but yeah, I'd rather be having to deal with coyotes than a big cat, anyday. I hope your stock stays safe tonight and from now on. We set up a game camera on one of the deer feeders in the back pasture and got TONS of photos of coyotes. It's a wonder how my barn kitties last around here. Guess they are smarter than the yotes. They are black so maybe that helps them lol! My older momma cat started losing her vision in one eye so now shes an inside house cat.. fat and lazy but very content not playing "I survived " every night 

Try some Night Guard Solar lights. 

Big cat.

I have some pictures that look much like yours. We had three dogs get into our herd of nannies. Thankfully, one had it's collar on and we had the owner tell the SO that it was missing. The SO had the owner come claim the dog at our place. He couldn't believe the death all around him. He claimed two of the dead dogs. His home owners kicked in and we were able to get a little cash to recover some of the loss. I tell you this in case you have dogs come calling. 

We live in infested hills. 3 types of cats, coyotes that fill the night with song, and now black bears are coming into the area. Our big problem-birds of prey. They can do the damage to newborns and they are relentless. I purchased a special gun that shoots bangers and screamers high up. Got some real hope this helps us. 

Hope you catch something on the cam. We get alerted quite a bit by our pictures when a big cat is in the area. We bring the goats and if we have foals into a big paddock with the lights for a time. 

My father in law lost over 40 head, nearly all his yearling ewes last year to the neighbor's dogs. 2 nights back to back. 1 was a border collie and the other is a mini aussie. Most had there throats ripped out. It was after a new snow and he was able to follow both dog tracks to the neighbor's yard about 5 miles away. 

It is strange for even a coyote to sit and gorge on one like that. Unless perhaps she has a den? Is it  too early for that? Our experience with sheep kills is they also kill or wound several and eat only the hind end and waste the rest.

But I really don't think cat??? Sorry this happened.

This might have been said already, but have you shown these pictures to the DNR?  Maybe they might have wildlife experts to help you...............

a shoulder and middle - it appears to be a cat kill - that is not coyotes.   

I'm so sorry.

one year we had one that killed a 600 weight steer (shoulder gone) and I found a beautiful doe of mine with her gut ate out....

go to   http://www.santacruzpumas.org/2014/03/lion-kills-vs-coyote-kills/ coyote vs cat kill - I tried to copy but this is pretty accurate.  cats  eat the internal organs first...  coyotes ususally start at the back end...  or google this to bring it up.

Deffinitely looks like a big cat to me. We have them take animals down around here sometimes. I'm not an expert, but in my experience, they look very similar to yours. Necks are usually snapped, sometimes theres marks, and sometimes not. They take a couple of days to eat the whole animal generally, but they always come back to finish. We left a half eaten calf out once, and the next day it was completely gone. We watched the cat eat it the whole day and drag just the hind end back in the woods. They don't leave anything behind. Like someone else has said though, they are slow eaters. Be careful! So sorry you are dealing with this.

Thank you for the help, I just dont know what to think anymore, I'm just on edge over all this. Could not get anybody out here to see for them selfs and I had a state trapper tell us its coyotes without even seeing the pictures, oh well got rid of the body last night.. The Game Wardens were not even interested, oh well.. Even when we had poachers it was like pulling teeth to get someone out here.

Have the other animals calmed down? Hopefully it was just moving thru and gone, whatever it was...I couldn't imagine how stressful that would be 

They do seem a bit more at ease, but the goats still wont go near their pen, but watching the Nanny's/Does they are still really watchy they keep looking over at that area and those poor girls just wont go over there, going to put up more wire panels and try to get them to go in but I'm really nervous about it to, they are still all sleeping in front of the hay barn and still leaving on lights, I'm always listening now for any noise they might make if being attacked, but like you I hope that what ever it was has moved on. Just nervous for my animals, really worried about my two mini's, they stay in with the big guys so maybe it will get back to normal in a few days/weeks, who knows

Havent seen anything attacked. But Lance has caught some pretty big cats on his camera. And not the one right dawn by the creek, but the one up the hill closer to the barn.
