Female Ina is genetically very valuable (seems a well advanced age to be breeding from)?
The former vice-director and curator for the big cats always said they were not allowed to breed with Ina because her line is to much represented in the genetic pool. Pepe turned 2 last week, so if breeding might work when he is 3 or 4, Ina will be 14 or 15 ... IMHO, that old age for a first time mum is pretty worrying.
