Re: My Feline Overlords
Recently one of the youngsters has begun bullying the oldest one
Are the cats neutered? Because, if they are not, then you introduce an extra level of tension in the group[1]. sadly, like with people, some cats just *don't* get along (our youngest delights in tormenting our oldest cat - but not to the extent that he's frightened. Also, I tell her off (in cat [2]) when she does and, since she's very human-orientated, she tends to listen to me. Over time, her behaviour has improved. We also don't feed them all together since food is another source of tension - 4 of our cats are perfectly happy to feed together, the other two, not so much. Youngest cat *really* objects to be given food or treats if the older tortie cat is around (to the extent of swiping at me even though she's my lap cat)
There are several possibilities why: She may have disciplined the kittens when they were first allowed to mix and, now he's bigger, he's paying her back [3]. Or, she's got an illness and her scent has changed (cats have a much, much better sense of smell than us) because he doesn't recognise her scent as one of the clan. One of our previous group of cats (a brother/sister pair plus an unrelated one) the sister started spending a lot of time next door and would come home smelling of slightly rancid chip fat and cigarette smoke. Her own brother attacked her because he didn't recognise her scent. We had to keep them apart until she lost the scent - at which point he was quite happy with her again. He wasn't the sharpest tool in the box but a lovely cat otherwise.
It's also rare for males to harass females [4] - they are usually much more interested in status & domination games with other males.
[1] Neutering toms is the quickest way to reduce their aggression. Our 2nd male is about 7kg in size and formidably armed. I suspect that, if hadn't been neutered, he'd be a bit of a Greebo.
[2] I speak fairly fluent cat - I can't do all the postures and, frankly, can't put my ears down flat against my head or lash my tail around. But I can do the vocal bits fairly well.. I also speak fairly good dog (with the same obvious limitations)
[3] I've seen this in our current 6 cats - senior cat (a male) tormented second cat (a female) when they were both youngsters - he's 3 months older than her so was a good bit bigger. She is now (they are both nearly 16 now) bigger than him and, when she did get bigger than him, she did pay him back..
[4] Females don't bother with all the posturing and shouting that the males do - they just go all-out to try to main the other cat. Presumably a hardwired protective instinct - why give an aggressor warning?
