A couple years ago a mulie doe ran out and smacked into the side of my truck one evening. I got out to check for damage to the truck in the deer. The deer was just laying in the road and there was no damage to my truck. I nudged the dears back and it jumped up and took off running and appeared to be fine. The Ditch at the edge of the road was pretty steep, and as the deer ran down the hill, I heard it fall. It had broken its neck and didn’t seem to be able to move, but was still alive, so I put her down. I’ve dealt with a few others that were hit by cars as well.
One time in college, a feral kitten was standing outside my door swaying. I think it had been bitten by a dog, it had a hole in the top of its head, and another under its jaw, and there were ants streaming in and out of its head, and it’s brain definitely had been affected. I ended up smashing it with a piece of firewood, and there were tons of maggots feeding inside the poor thing s head.
My sister runs a cat rescue. She’s brought me a few cats to put down that were removed from cat hoarders where they had been inbreeding, some were blind, some had missing legs, some were paralyzed, etc. she said there were other cats that were in the process of being eaten, as well as skeletons. Pretty sad for the cats, but also sad for the people that live in those conditions, huge piles of poop against walls, really everywhere, and terrible urine smell.
