Introduction: this is a guest article from about 2010 which I have republished as today April 21, 2022, I am writing about feline aggression.

Sexual aggression 2
Sexual aggression 3
The incident which I am going to narrate out here is between two male feral siblings, both aged around eight months.
Feral one is brawny, aggressive and avoids actual human contact.
Feral two is skinny, less aggressive and prefers actual human contact.
These kittens were left to fend for themselves when they were nearly ten weeks old by their mother after teaching them survival skills.
Now they know how to survive in the ghetto they were born in.
The "Tom Cat" father of these siblings is found occasionally walking around majestically and the siblings notice him.
Skinny feral takes flight, but the Brawny feral actually walks behind sniffing his father's testicles, while the father ignores him and continues to walk ahead, flicking his tail.
Conclusion: Tom cats accept their kids hanging around in their territory.
When the feral siblings are mewing out loud near my main door for their night meal, their father walks towards them mewing back.
Brawny feral son walks to his father rubs nose, then father leaves, skinny feral son avoids all contact with his father.
Skinny feral (my favourite), is intentionally not fed while I deliberately feed his brawny sibling indoors.
When I close the main door trapping both feral brothers indoors the brawny feral not used to being indoors like his skinny feral brother, shows signs of panic, desperately finding exit hole.
This panic and sense of fear seen in the brawny feral, makes the skinny feral leap on him and mount him as if it was a female cat, and starts humping his back (masturbatory behaviour) without actual penetration.
This behaviour continued for about ten minutes with short gaps in between.
This passive acceptance by the aggressive and brawny sibling would not have taken place under other conditions.
Conclusion: expression of aggression by the inferior cat via sexual means is a matter of further research.
