Apparently, I'll need a mediator.
From my observations, it's more often than sometimes. Just the other day I smacked my moms male cat for pinning down and trying to rape one of the other male cats. One of my brother's dogs is always trying to hump the other male dog who is also his brother. Animals in general I don't think have many concepts, level of awareness, or care or concern about many human ideas of sex. It seems about the only similarity in regards to sexuality is that animals, especially social animals, just like getting laid (especially bonobos).
