Lance, I didn't take any other photos. I was trying to get to work and a ways from home.
There is a wash about 10 yards to the east of this toilet, that runs north and south. On the west bank of the wash, there are two large bushes/trees. I don't know what they are (and it probably doesn't matter) but they look like a cross between scrub oak and holly. Anyway, there is a 5 foot space between these two big bushes and that's where the toilet is. So I put a walk through in the wash and blocked it down so anything coming up or down the wash near the toilet would get caught there.
As to the toilet itself, it was a little closer to one bush than another, so I blocked it down in two places about 5 feet apart, with the toilet in between the two sets. Then I applied lots of gland lure to the droppings, some skunky lure on an elevated bush between the two sets, along with a castor based lure low and just inside the blocking on each set. Lots of polyfil.
So if the cat comes down the wash and looks right, he sees poly and gets a whiff of the skunk, etc. If he approaches the sets, he sees the droppings/toilet but has to walk through the set to get to the toilet. On the other hand, if the cat approaches from the west, he has the same dilemma -- has to walk through the set to get to the toilet.
Make sense?
