I love the males also. I have 8 male cats. 3 female cats. They are neutered, and even the last one that came to live with me, which was an intact male stray cat (neutered as soon as possible, but it took 3 weeks for appointment) and I have never had a problem. Now, since you are talking a breed rescue, vs. just a "mutt" cat rescue, a lot of the times the cats were used for breeding and have traits sort of "drilled" into their personality. This may be what she is concerned with. Personally, I would have a red flag warning if any rescue agency said I have to KEEP THE NEW CAT if something went wrong. All the associations around here (and there are A LOT) will take back their cats willingly if it does not work out. So I would say that your biggest concern ISN'T whether you cdan or should get a male, it should be WHERE do I get him from.
