Well yesterday I went out to feed our full sized horses (there are 10 of them together right now on 14 acres) and I noticed our arabian mare, Xcia come limping up behind everyone else. She had two rows of large gashes on her back and over her butt, down to the tailhead. I caught her and brought her up front, and realized that it was deep scratches. We called the vet out and had her doctored up, two scratches were deep enough that it tore into muscle and had to be sutured, but most were superficial. She has an ointment to use, bute, and was administered some antibiotics for infection so she'll most likely be fine, but it made me wonder.
The BO, vet, and I think that it was probably a bobcat, since one has been lurking around here for the past year and has been looking very thin due to lower small animal population (its forever trying to get into our chicken coop along with the coyotes) but...why would it attack Xcia, a 14.3hh 900+ pound mare? And especially in a herd setting? I could see if it had no other choice, but we have an entire pasture of miniature horses, including a dwarf and a three month old foal, just across the creek. Why wouldnt it go after those? O.o
