Oh dear I was so upset when i read this thread... perhaps it's not so much the cats but other unresolved issues that they have? (Sorry.. it's the therapist in me talking) I believe that apart from rolling up the rugs and seeing a vet etc. a couple has to accept each other (and that includes pets!) completely before living together. My hunch is that there are other issues that perhaps need to be sorted out. When he loves her for who she is and does not try to impose his standards on her (yes, I'm just guessing here - sorry) the cats really shouldn't be an issue. In fact, if i knew that my boyfriend had the same problem, i would try to help him take care of the kitties!! Good luck to your friend, and please keep us posted about the kitties, ok?
