So I have two male Syrian hamsters father and son they have been together since birth and ever since my hamsters mom passed away he started to become closed off but when I separated them from the cage he lived in where he grew up with his dad he just shut down and would not eat as often ,exercise or let me near him even though previously he was quite tame but after a few months I saw how scared and unhappy he was and tried to reintroduce them he instantly went to his dad and they both got together well even after I kept him there for a week I saw him eat with his dad more often and also exercise in his wheel so I decided to keep them together since he seems to do way better with his dad than alone so is this still a good idea ?
