I live adjacent the Superstition Mountain Wilderness area in central
Arizona.

We get a lot of wildlife traveling through our backyard including
typical desert fauna: coyote, wild boar,etc.

I spied a cat today as it cruised through our backyard, I would guess
about a 30 pound ( estimated standing height 22") animal proportioned
like a housecat except: Its legs were longer, it had tufted ears like a
bobcat (no lower whiskers though) and a bobbed (about 4" long) tail
that stuck up and curved forward on the cat. overall coloration
grey/brown topcoat with vertical darker striations that were not quite
stripes (tabby-like)the tail was white on the rear as were the backside
of the lower paws.

This cat had a lean build.  I am very familiar with cougars, ocelots
and lynx, this appeared to be niether.

I've spent time on the web and found no matches, Any thoughts?
