How did you find that out?

Kipling told him.

A friend told me who works in a cat charity

You hadn't noticed that your 'male' cat was missing it's and balls before this? Or is this some sort of feline intergender situation, like a cat version of Caster Semenya maybe? Catster Semenya?

Mother's friend had a cat called Saara (girly name) and one time at the vet's they found out it was actually male.

That's okay, I have a female dog that humps male dogs.

That's not a sexual behaviour, it's a display of dominance, to show whose boss and establish placing in the pecking order.

Actually, the h*mping can also be a sexual behavior. As dogs both do it when theyre in heat, both males and females. I know this, Ive had an unspayed little bi**h living with me for the last 8 years.

Also, dogs h*mping ppl they love or is attached to is like an affection of love and gesture. Again, I get my arm humped every time we lay together.

Back to the discovery at hand..

You are preaching to the choir, I know the reason is that she is the oldest dog out here and she is the alpha female.

This happened to the brat. She's got two kittens, both adopted as females. One has turned out to be male, and is now twice the size of his sister.

mine tried to hump me when she was in heat too... when I was on my period it was even worse. like she thought I was also on heat... I got her sterilized 7 months ago so that's stopped now

Atleast it didnt come home pregnant
