Need to add one more thing ... there is one more difference in our local market when buying Grey Africans ... the wild and tamed ones
Wild one : won't let you get near it and attacks fiercely plus gives a growling squeak
Tamed ones : donot sqeak at all, may bite but in self - defence only ... would never purposely attack
This is a tamed one, never ever squeaked or growled and does not bite when caged but outside the cage it is selective and takes time to get accomodated.
