Hi ,personally I'm quite confused on what you're actually trying to convey but overall I think you're trying to say that the previous owner wants him back? If it's like that then you should definitely compare the care provided by u and that owner. And if you think that owner is kind of negative then pls dont make that hamster suffer ,make him live where he'll seriously enjoy it.
*no hate* Umm I'm really sorry if my ans is not what you expect, it was difficult for me to understand what you said.
