That is a huge tom bobcat!!! A lynx is actually lighter than a bobcat in there build, they are real thin and lanky, but Bobs are stouter, shorter with a worse attitude. He's likely to push the 50-60lb range.
I have had to release a couple cats in that size range they are impresive there front legs are the size of your arms, they will tear you up if you don't fling and run! I would rather tangle with a MT lion than that dude any day of the week!!
Real cool pic !!!
