Help with aggressive female

[yetanothernewusername1]

Hoping to get some advice from you knowledgeable lot....

A pregnant female cat moved in in November....I already have 2 male cats, neither aggressive in anyway. Things were fine between the 3 then she had her babies in December....

We kept mum and kittens separate and on the one occasion one male got in the bedroom and she went for him. I understood she was protecting babies so more effort went into keeping them all apart.

Fast forward and the kittens have gone now bar one we have kept but there have been several other occasions she's gone for the same boy cat, never the other. This happened on a few other occasions.

It's now usually food related, she seems to get very aggressive but I know a bit about the circumstance she's come from and it's highly likely she's just used to having to fight for food.

My boy is now terrified and won't come in if she's around. I have to physically put him in kids room.

I'd have been happy keeping her around if it wasn't for this major issue, my boy was here first!

Any ideas? She does actually belong to a woman a few doors down with 10+ cats. She's alcohol dependent and has been known to punch neighbours at their doors so I really really don't want to have to go there!

Is the cat neutered now?

Can you feed the female cat in a different room from the male cats? If she isn't neutered yet, please get that done.

She's not my cat! Can I go around getting other people's cats spayed? And yes boys are neutered.
Been feeding separately but it's all such hard work I just wondered if there we any other ideas?

I’d do it for the cats benefit. Just keep her at yours till the fur grows back.

Honestly, she’s effectively your cat now. Get in touch with your local Cat Protection branch (if you are in the U.K.). They can advise and potentially help you with getting her neutered.

Ok, that I can do thanks...
Will this settler her down do you think? Like I said I don't mind her staying but my boy has to feel safe in his own home! We still have one of her kittens but I genuinely don't feel it a protective instinct.

It calmed my male down and made him more affectionate. It took a couple of weeks for the testosterone to wear off.

Of course you need to get her neutered or there will soon be another litter of kittens adding to the cat overpopulation problem!

@viccat yes all well and good when you own the cat but I don't! Mine got done as soon as they could!

She clearly didn't feel safe having her kittens with the woman a few doors down so she had them here that's fine but she isn't mine, she lives there!

Genuinely didn't think getting someone else's cat spayed was the done thing but a pps idea of keeping her in until her fur grows back is a good one.

It’s exceptional circumstances though & repeated pg then labours with no pain relief can’t be nice.

The owners too off her face to do it by the sounds of it.

What did you do with the kittens, sold them? It just seems strange you were happy to care for the kittens, kept one, and would keep the cat but worry about getting her spayed...

Oh actually @viccat I can't actually be doing with your sanctimonious shit. What I'll do is next time a heavily pregnant queen is wandering the streets at 4am waiting outside my door I'll leave her to freeze!
I never sold any kittens, they have gone to family members and yes I had intending on caring for her whilst vulnerable but time to do something practical!
I asked for advice on here that's all.
