It has now been two months since I have suspected

.STRESS
Two months ago all her behaviour indicated that she had lost her babe. With the presence of wild dog and male lion in the immediate area, who knows what happened.
My suspicions turned into a more sinking feeling when she was still in the same area the following day and no longer calling for her babe.
Yesterday afternoon she was seen courting Mvula which is all the proof we need that her last babe didn't make it.
It will be a three month wait till she manages to replace what she has lost, hopefully she will have two cubs in her new endevours at motherhood.
