Thanks for the feedback, its been fun going through all the posts and i now feel like i know a lot of these leopards through all sightings of the many forumites!
The original picture from Sivet would help a bit but I'm completely convinced. I've found that if they are the same leopard then spots fall into place all over the show (kind of obviously!) but if they aren't the same then it is very hard to even find anything that might be a small match.
So my own personal sightings, first I'll start with the 13th Bore hole cub and mum. I was fortunate enough to see them on my second trip to the park on 16th July 2011 at the Rooibrak water hole (is this the 13th Bore hole?). I was in the park with a friend (Garry) on a drive out from TR. We were nearing our turn around point (and i have to admit i was dosing a bit

) when Garry pointed out a cheetah on the right....well it wasn't a cheetah but a female leopard
Mum

After about 5 minutes of watching, Garry again...and to my shame...pointed out another leopard about 3m the other side of my open window

The leopard, the cub, was lying down eating the remains of a kill (reported by some other people in the park to be a stolen springbok from some cheetahs).
Cub: Miera

We proceeded to watch the two leopards wandering from the trees and pump on the left to the water hole on the right. 30mins of uninterrupted bliss . At times i didn't know where to look as they were on different sides of the car.

Eventually they decided enough was enough and they wandered up the hill...this coincided with the arrival of another car.

We followed them along the ridge for a few 100m but they eventually disappeared.
