Actually the male would be the one to make the fuss. It is rather rare for a female to roam and push for breeding reasons. They give off the pheromones and the males make the effort. The males will combat, stop eating and channel their energies into finding a mate.
Gerald is younger than his girl and I'm not even sure if he has hit full maturity.
JM has already moved cages around, separated them by room and kept her out of the cage. When she is out of the cage she typically is fine, and she isn't roaming looking for the male's cage according to JM.
I'd find it unlikely this is a female wanting to breed. In almost all species of animal, the males make the effort to breed and have to be accepted by the female.
It's a larger subject than that explanation however, Gerald would be the snake making the ruckus in this situation.
