In our magazine "Georgia Outdoor News", there was an article about a guy here in Georgia that was carrying firewood back to a house from a woodline, when he heard something behind him. As he turned around, a medium size bobcat pounced on him and hit him square in the chest. The bobcat began clawing and biting as the guy attempted to pull him off. He eventually fell down (on top of the bobcat) during the struggle and put the cat in a death choke hold. After about a minute, the cat stopped breathing, but the guy maintained his grip around the cat's throat for another 5 minutes, just in case. (Can't say I blame him). The cat was able to bite and claw through his carhart jacket and leather gloves. The guy received numerous cuts and bites, but did not receive any major damage. Later reports indicated the bobcat was rabid (no shock there) and the guy ended up having to have the dreaded series of shots. The article indicated that the first rounds of shots included 13 shots directly into each of the deep cuts and bits. However, the following shots were the single series.
I've had a few come in on me, but once they realized I was there, they've sneaked off. Several have let me know they are there by getting vocal (high pitch sounds and spitting), but I've never had any approach me with the intent to take me out of the game. (Doesn't mean that they haven't scared the crap out of me at night when they've closed within 10 yards)
It sounds crazy, but around here (in Georgia), I'm much more worried about being hit by a rabid fox than I am a bobcat or yote. Out numbers of rabid fox have increased during the last 10 years or so to a point where we have reports pretty often. While I've called in yotes and bobcats to under 10 yards numerous times, I can usually see them coming in. The fox on the other hand, are harder to see as they approach in taller grass, and I've had some run across my feet before I knew they were there.
In closing, the only things that I've been recently attacked by was (1) a large horned owl that dived on me when using an open reed call. He angled off a fraction of a second before nailing me and the tips of his wing brushed my hat. AND (2) an annoying bat. I was using the IR feature on my night vision monocular, not realizing that bugs are equally attracted to IR light. I had a great swarm of moths and skeeters flying around my head, when all of a sudden I kept hearing this fluttering that kept going past my head. After several times (and remembering my encounter with the owl), I turned on the red filtered light to see what in the heck was going on. I immediately saw that I had this over energetic bat that was making meals out of the flying insects that were swarming around my head.
