13 Y/O rabbit and (I think, I'm horrible with birth dates) 14 Y/O rabbit. Will we work?

Hi, if you are both rabbits, you need more efforts to achieve a steady relationship, because both of you are realistic. Uon the difficulties, I suggest you try to discuss and find a final solution, instead of leaving it alone, by which you can have a peaceful life.
Well, if she is a tiger, you need be more considerate to the tiger so that she can live long with you.
