There's not many reports of bear in Central Texas. I'd vote for the cougar. They follow the deer population. Most rodents work the antlers over quite a bit. Wood rats, field mice and pack rats really like to gnaw on antlers.
As will porcupines.Yet.
Squirrels will eventually eat the antlers.
Life story here... Hogs do eat meat as most people don't realize, but some time ago I lost a bet with y Father-In-law, I had just shot a big bore coon off a gut pile and brought it home to skin it out, he bet me his hogs wouldn't eat that Raccoon, guess what - they wouldn't eat it - they just pushed it down the wash out at the bottom of the pen.A number of years ago in east NC I shot a deer 120 yards from the stand. I was hunting on a logging path between two thick cut overs. Deer fell just off the edge of the path where the weeds etc. were about 3 feet high and I could not see the deer from the stand. I shot this deer about an hour and a half before dark. We can kill more than one deer a day so we always stay in the stand until after dark. There are no coyotes in this area, at least we have never seen one or any sign or heard any. When I got to the deer a total of just under 1 1/2 hrs after killed half of one ham had been eaten. My buddy and I figured it had to be either a fox or bobcat. A couple years later I killed a deer from the same stand at about the same yardage but deer falls in the path where I can see it. A little while after the kill I look down there and there is a fox standing up on my deer. I know it is going to start eating so it gets a 117 gr Sierra from my 25-06. Picked it right off my deer.
When I was in college I went home with my roommate to his home for a visit over Christmas break 1978. He lived in Indiana. His dad owned a big dairy farm and there were some feral dogs that were running in a pack on his farm and had killed one of his calves and were chasing his cows. There was a very deep snow but we decided we needed to go out and see if we could kill some of those dogs. His dad got out the big tractor that sat way off the ground and could get through the snow and we all piled on. He had seen the dogs in an area that was a low usually wet area that had lots of brush etc in it. We set up a L shaped ambush around this area and he drove the tractor into part of it. Out comes a bunch of dogs running and because there was about 6 inches of fresh snow on top of a frozen layer of ice that covered the other 4 or so feet it slowed the down and gave us better shots. We are all armed with shotguns shooting like #5 and 6 shot so killing them outright was a close range situation. We get three of them outright but do get a couple running off yelping. My roommate's brother in law was with us and he had a hog farm. He tied the dogs on the tractor to get them back to his truck and he took us to his hog farm just down the road. He said watch this and took the dogs and ripped open their gut with a knife and tossed them into the hog lot. It looked like a Tarzan movie when someone was being eaten by prana. They tore those dogs apart and ate them leaving nothing but bones in short order. Blew my mind.
That's wack. They are smart, it is said they are about the same or more intelligent than dogs....I put a trail camera on a deer carcass in a north Louisiana pine thicket and got a video of a boar hog burying the carcass and come back and feed on it throughout the week.
