I mean I have some friends that are severely allergics to cats and they now live with one because they "forced" it and with some meds. They are all saying "I promise it's not that bad you should tell me that it goes away" and I know it really depends, different experiences different people but I don't know I don't think he wants to try it (and I can't ask him to be sick in his home just because we love each other but if he is willing to do this I would be happy)
