I have seen a lot of bobcats in the wild and that top one is as big as I have ever seen.
Without context of how big any of the stuff around it is, how on earth do you come to that conclusion?
It looks skinny. That's about what you can tell from this picture.
I sent this to a lot of my buddies that do varmint hunting contests and everyone of them said that is one of the biggest cats they have seen. This cat lives near a spring fed creek that is never dry and always stocked plus an abundance of little critters so I doubt it's too hungry.
