Looking for some more learned opinions. This was sighted this afternoon in Dutchess County. Based on some shots of the same or similar cat (carrying off what appeared to be a friendly local pet domestic cat last week) next to some measurable landmarks this cat is 20 inches at the sholder with a body of about 36 inches in length. The curved tail much longer than a 5 inch bobtail. There are no obvious telltale bobcat spots. Compared to dog of similar size I would guess a weight of 40 to 50 lbs but it could be more. The picture is not great but it is the best of several options.
