I was wondering, how do male neuters act/react toward a female queen in heat??

3 of mine ignore them, one if he could tries to hump them (but doesn't actually get as far as doing anything, just jumps on them and mouths the back of their neck). I do not let them mix together though, as the females are more likely to whack them one.

I have 2 neuter boys, 1 ignores the calling girls the other serenades, yodels and mounts them.
My girls don't mind him at all.

I had a neuter that used to breed the girls of his choice!

LOL Chocolatedots!! I'm having a giggle imagining yodelling Ocicats - you know, making that Tarzan noise, swinging through the trees and jumping on one of your girls!! Perhaps I have an overactive imagination though.

Jemappelle - the cats in your avatar are just beautiful.
