Thank you all for the comments.
We were now just about ready to see a spotted cat and a honey badger and pygmy falcon would be nice too.
We decided we will go as far down as dertiende boorgat and then back track to camp.
But for us it was going to be a day for lions. Two young males had sought out the shade of a tree bang in the middle of the road.

We watched for a while and one of them gave us a lazy lion yawn

then went back to sleep.
As we still had plenty of time to gate closing we assessed whether it would be safe (for them and us) to pass the lions and head for dertiende
boorgat. We inched closer and could see tyre marks on the side of the road where somebody had already passed. We slowly and carefully passed them and my daughter clicked away as we moved forward.
The expression on the lions face said, can't a guy have his siesta in peace

Come now get done with it will you

At this point we could see that the lion that was closest to us had a porcupine quill in his cheek.

The lions were only interested in their sleep and we were soon pass them
which brings me to another snippet from my KTP guide book. Research done on the Kalahari lion shows that he kills three times more animals per year compared to his KNP cousin although the KTP lion kills far more smaller animas (squirrels, bat eared foxes, porcupines etc.). The KTP terrain makes it more difficult to kill the larger animals which are fewer in KTP anyway. Porcupines account for about 25% of the animals killed.
The trip to veertiende and dertiende boorgat was unproductive and the lions were still there when we returned in about half an hour and so was another car, enjoying the young males.
On our way back to camp we met up with Wanderw - hi there - and exchanged notes. She told us about the cheetah at Sitszas waterhole and we told her about the lions at Dalkeith and the young males on the road.
Cheetah.............we were excited.
