Hi, this is my first post but I’ve searched the site & found a few threads on sexual aggression in neutered males but I’m not even sure that’s what this is.
We have 6 cats, all neutered males, 5 have lived together happily for years with the occasional playtime taken too far kind of fuss. Last week we introduced cat #6, a 3 year old Siamese mix male. The shelter said he was previously neutered so idk how long ago that was. Honestly I’d guess could be anywhere from 2 months to 2.5 years ago. He was very calm at the shelter and was doing great in their adult cat room getting along with the others.
He’s overall extremely calm at home too, and I will say up front we do introductions absolutely wrong. We separate them very little and let them get to know each other at their own pace. Our house is only 1400 sf but they do seem to have plenty of room to be apart when necessary, they have plenty of vertical spaces, food and water are scattered around the house and we have 4 litter boxes for 6 cats. I work from home & spot clean them multiple times a day plus 2 big cleans. There’s been a little marking in the house but not too bad & definitely not unusual for the first week of bringing a new cat home.
Everyone is eating, drinking, laying near each other for naps, some playing and plenty of asking for pets, etc. The only real problem arises when the new cat seems to get it in his head that he needs to bite the neck and try to hump one specific other cat. His victim is the dominant one I’d say and at first I assumed it was just a little challenge from the new guy to establish pecking order. But it’s WEIRD. Being Siamese he’s very vocal and I can tell from anywhere in the house that he’s in one of his moods bc of his very specific “trill” kind of musical chirping. His eyes are always dialated and then he pounces, tries to hump while biting the neck and his victim fights back. Twice I’ve squirted small puffs of spray from a water bottle at him when he sinks his teeth in the others neck & he absolutely respects that & stops, while not seeming to hold a grudge against me at all. It’s almost like he snaps out of a trance. Even with this occasional behavior everyone is incredibly well adjusted and calm I think but I don’t want his preferred victim stressed out.
So my basic question is, does this sound like sexual aggression and if so what’s the best way to put a stop to it? I’ve got Sentry collars on him and 2 other cats but not the victim cat bc he’s usually not one to pick fights. Should I get another 3 pack & put them on ever6 cat just to be safe? I’ve got 1 feliway diffuser going all the time, and I have another that drips a lot so I’m reluctant to use it but I could always buy another new one.
Should I be worried he’s a cryptorchid and have my vet do an ultrasound or whatever they do if they think he might have testicle tissue inside? I can’t help wondering... but then again maybe this behavior is common among males when they’re getting to know each other?

is almost always trying to establish territory and pecking order. I don't think it is sexual, but domineering. The nondominant cat will eventually fight back or not be a victim anymore, but I know it is a hard thing to watch. One thing I thought of is you might go to a farm supply store like Orschelns or Tractor Supply and get an anti itch spray that has a bitter taste in it to discourage licking and biting. If your newcomer gets a mouthful of that when he bites the neck he won't like it and the other cat will never know because it is on the back of his neck and he can't reach it. I accidently had some on my fingers from spraying it and it is terrible! Just make sure it is for cats. You might put a Sentry collar on him too, to block his neck a little.
It was definitely that, not pee or whatever.
