4 available female gerbils, 3 are bonded and must go together. The white, orange, and grey have been together since babies. About 5 months old. I have a solo black female I wasn't able to bond to the other three. 30 for the trio. And 15 for the black female. Will sale with complete set up for the trio for 200 and all excess supplies. Have way more money then that into all the accessories and cage. The black one can include its water/food dish, house and wheel for 35. Not the cage though cause it was temporary and to small for long term. Text with questions.
