I agree, that it sounds like you are doing the best that you can. As a stay at home mother, who is usualy home, I too have to admit that there are times when my ratties do not get alot of out time. If I have an ill child with something that I think might hurt the rats they do not get much people time durring that time. But we make up for it as soon as we can, and they do have rat companionship always. Think about the alternative. If you were to place them, you can never be sure what kind of care they are given in their new home...I would just keep doing your best, as you already are.
