Looks like a bobcat to me too. I think you can see the tail tucked under it back legs. Chin and neck look colored like a bobcat too. Where's a bigger pic of the important photo?
I would have to say bob cat. You can see the coloration on the back legs and the throat area. It sure looks like a big bob cat though.
You're the only one that can get an idea of the scale Dubbs, my first thought was cougar. I don't see any spots on it and those feet look big compared to the body / leg size. Put a meter stick where it's standing and get another pic for size comparison. Like you said, too bad you can't see the tail.
Get a better trail camera. I could see that being a mountain lion but Greg has saw more bobcats then most so I'd say listen to him.
I guess this boils down to whether this is a bobcat or cougar. Where was this pic taken? Do you have cougar in your area? Cougar are far less common than bobcat also I think I'm seeing spots up front on the cat, so, I believe it's a mature Bobcat.
Looks like Puma Concolor to me. The head appears to be more rounded than a bobcat and the pale white underbelly just appears to be more in line with a Mtn Lion. Not to mention it's posturing and the lack of visible stripes or spotting on it's coat.
... OK, here are my thoughts. I think I can even see the black of his lips behind the ball. Canis Domesticus
