I have never heard of that, I had an intact female living with in intact male for 2 years, and nothing of the sort ever happend.. but then its not as if Misty has ever WANTED to mate with Blair, he has only been neutered for 2-3 months now, but when he was intact he walys tryed to get with Misty because she would have no part in it, it made keeping them seperate simple lol
