Hi all...recently i came across a female himalayan cat. The previous owner had to get rid of her and instead of letting her go to the pound i took her. The owner said she had been to vet before--foudn out that was a lie. They also said she was spayed. Well, last night i noticed some signs of heat...she is vocalizing alot more and also rubbing her rear on furniture and whoever is petting her. Anyhow, i also have 2 other cats...males...both neutered. Well, today i went into my den and found one of the males on top of her. They keep going back to it. I was wondering if this could result in pregnancy? He is about 11 months old, got him fixed about 3 months ago. I had seen before that a neutered male could still reproduce up to a month after, but 3 months? I seperated them, but when i left to run errands i came back and he was on top of her again. I was just wondering why he has any kind of sex drive and/or can he actually still get her pregnant?? please let me know, ty
